The quality control functions in MassWateR can be used once the required data are successfully imported into R (see the data input and checks vignette for an overview). The required data includes the results data file that describe the monitoring data and the data quality objective files for accuracy, frequency, and completeness. The example data files included with the package are imported here to demonstrate how to use the quality control functions:
library(MassWateR)
# import results data
respth <- system.file("extdata/ExampleResults.xlsx", package = "MassWateR")
resdat <- readMWRresults(respth)

frecompth <- system.file("extdata/ExampleDQOFrequencyCompleteness.xlsx", package = "MassWateR")
frecomdat <- readMWRfrecom(frecompth)
#> Running checks on data quality objectives for frequency and completeness...
#> Checking column names... OK
#> Checking all required columns are present... OK
#> Checking for non-numeric values... OK
#> Checking for values outside of 0 and 100... OK
#> Checking Parameter formats... OK
#> Checking empty columns... OK
#>
#> All checks passed!Creating the review report
The qcMWRreview() function compiles a review report as a
Word document for all quality control checks included in the MassWateR
package. The report shows several tables, including the data quality
objectives files for accuracy, frequency, and completeness, summary
results for all accuracy checks, summary results for all frequency
checks, summary results for all completeness checks, and individual
results for all accuracy checks. The report uses individual table
functions described in the sections below to return the results, which
include tabMWRacc(), tabMWRfre(), and
tabMWRcom().
The workflow for using this function is to import the required data
(results and data quality objective files, as above) and to fix any
errors noted on import prior to creating the review report. The function
can be used with inputs as paths to the relevant files or as data frames
returned by readMWRresults(), readMWRacc(),
and readMWRfrecom(). For the former, the full suite of data
checks can be evaluated with runkchk = T (default) or
suppressed with runchk = F, as explained in the relevant
help files. In the latter case, downstream analyses may not work if data
are formatted incorrectly.
The report can be created as follows by including the required files and specifying an output directory where the Word document is saved (a temporary directory is used here). Once the function is done running, a message indicating success and where the file is located is returned. The Word file can be further edited by hand as needed.
qcMWRreview(res = resdat, acc = accdat, frecom = frecomdat, warn = FALSE, output_dir = tempdir())
#> Report created successfully! File located at /tmp/RtmpbPaSat/qcreview.docxAs a convenience, the input files can also be passed to the
qcMWRreview() function as a named list using the
fset argument. This eliminates the need to individually
specify the input arguments.
# names list of inputs
fsetls <- list(
res = resdat,
acc = accdat,
frecom = frecomdat
)
qcMWRreview(fset = fsetls, output_dir = tempdir())Note that the warnings are suppressed above with
warn = FALSE. By default, this argument is set to
TRUE to view the warnings in the R console after the report
is created. The warnings indicate notable concerns to consider for the
input data that may need to be addressed. Details on these warnings are
described in the sections below for each quality control table.
Optional arguments for qcMWRreview() that can be changed
as needed include specifying the file name with
output_file, suppressing the raw data summaries at the end
of the report with rawdata = FALSE, and changing the table
font sizes (dqofontsize for the data quality objectives on
the first page, tabfontsize for the remainder).
Quality control for accuracy
The quality control checks for accuracy assess several
characteristics of the data in the results file by referencing
appropriate values in the data quality objectives file for accuracy. In
short, the accuracy checks evaluate field blanks, lab blanks, field
duplicates, lab duplicates, lab spikes, and instrument checks. The
accuracy checks require results data (as in resdat above)
and data quality objectives files for accuracy (accdat) and
frequency and completeness (frecomdat).
The tabMWRacc() function is used to create tabular
results for the accuracy checks for each parameter. The function can be
used with inputs as paths to the relevant files or as data frames
returned by readMWRresults(), readMWRacc(),
and readMWRfrecom. For the former, the full suite of data
checks can be evaluated with runkchk = T (default) or
suppressed with runchk = F, as explained in the data
inputs and checks vignette. In the latter case, downstream analyses
may not work if data are formatted incorrectly. Also note that accuracy
is only evaluated on parameters that are shared between the results file
and the data quality objectives accuracy file. A warning is returned if
there are parameters that do not match. The warnings can be suppressed
by setting warn = FALSE.
The tabMWRacc() function can return three types of
tables as specified with the type argument:
"individual", "summary", or
"percent". The individual tables are specific to each type
of accuracy check for each parameter (e.g., field blanks, lab blanks,
etc.). The summary table summarizes all accuracy checks by the number of
checks and how many hit/misses are returned for each across all
parameters. The percent table is similar to the summary table, but
showing only percentages with appropriate color-coding for hit/misses.
The data quality objectives file for frequency and completeness is also
required if type = "summary" or
type = "percent".
For type = "individual", the quality control tables for
accuracy are retrieved by specifying the check with the
accchk argument. The accchk argument can be
used to specify one of the following values to retrieve the relevant
tables: "Field Blanks", "Lab Blanks",
"Field Duplicates", "Lab Duplicates", or
"Lab Spikes / Instrument Checks". Below shows how to
retrieve each table using the data frames from above for the results and
quality objectives file for accuracy. The warnings are suppressed with
warn = FALSE.

For type = "percent", the function returns a similar
table as for the summary option, except only the percentage of checks
that pass for each parameter are shown in wide format. Cells are
color-coded based on the percentage of checks that have passed using the
percent thresholds from the % Completeness column of the
data quality objectives file for frequency and completeness. Parameters
without an entry for % Completeness are not color-coded and
an appropriate warning is returned. All accuracy checks are used and the
accchk argument does not apply.

The tabMWRacc() function uses the
qcMWRacc() function internally to create the table. This
function creates the raw summaries of accuracy from the input data.
Typically, qcMWRacc() is not used by itself, but it is
explained here to demonstrate how the raw summaries can be obtained.
Below, the qcMWRacc() function is executed with the data
frames for the results and quality objectives file for accuracy. As with
tabMWRacc, the accchk argument can be used to
return one to all of the checks. The results are returned as a list,
with each element of the list corresponding to a specific accuracy
check. Here, the lab duplicate checks are returned. The warnings are
also suppressed.

The quality control checks for frequency are used to verify an
appropriate number of quality control samples have been collected or
analyzed for each parameter. These are checks on the quantity of samples
and not the values, as for the accuracy checks. The frequency checks
require results data (as in resdat above), a data quality
objectives file for accuracy (as in accdat), and a data
quality objectives file for frequency and completeness (as in
frecomdat).
The tabMWRfre() function is used to create tabular
results for the frequency checks for each parameter. The function can be
used with inputs as paths to the relevant files or as data frames
returned by readMWRresults(), readMWRacc(),
and readMWRfrecom(). For the former, the full suite of data
checks can be evaluated with runkchk = T (default) or
suppressed with runchk = F, as explained in the data
inputs and checks vignette. In the latter case, downstream analyses
may not work if data are formatted incorrectly. Also note that
completeness is only evaluated on parameters that are shared between the
results file and the data quality objectives completeness file. A
warning is returned if there are parameters that do not match. The
warnings can be suppressed by setting warn = FALSE.
The quality control tables for frequency show the number of records
that apply to a given check (e.g., Lab Blank, Field Blank, etc.)
relative to the number of “regular” data records (e.g., field samples or
measures) for each parameter. A summary of all frequency checks for each
parameter is provided if type = "summary". The function is
executed with the data frames for the results and quality objectives
file for frequency.

#> # ℹ 30 more rowsThe output shows the frequency checks from the combined files. Each
row applies to a frequency check for a parameter. The
Parameter column shows the parameter, the obs
column shows the total records that apply to regular activity types, the
check column shows the relevant activity type for each
frequency check, the count column shows the number of
records that apply to a check, the standard column shows
the relevant percentage required for the quality control check from the
quality control objectives file, and the met column shows
if the standard was met by comparing if percent is greater
than or equal to standard.
Quality control for completeness
The quality control checks for completeness are used to assess the
number of regular samples relative to qualified samples that apply to
each parameter. Regular samples are those with
Field Msr/Obs or Sample-Routine in the
Activity Type column of the results file and qualified
samples are those marked as Q in the
Result Measure Qualifier column of the results file. The
completeness checks require results data (as in resdat
above) and a data quality objectives file for frequency and completeness
(as in frecomdat).
The tabMWRcom() function is used to create a table that
shows the completeness percentages for each parameter. As explained in
the previous section, the function can be used with inputs as paths to
the relevant files or as data frames returned by
readMWRresults() and read_frecom().
A summary table showing the number of data records, number of
qualified records, and percent completeness can be created with
tabMWRcom(). The % Completeness column shows
cells as green or red if the required percentage of observations for
completeness are present as specified in the data quality objectives
file. The Hit/Miss column shows similar information but in
text format, i.e., MISS is shown if the quality control
standard for completeness is not met. The function is also executed with
the data frames from above, since they have already passed the internal
checks.

Each row applies to a completeness check for a parameter. The
datarec and qualrec columns show the number of
data records and qualified records, respectively. The
datarec column specifically shows only records not for
quality control by excluding those as duplicates, blanks, or spikes in
the count. The standard column shows the relevant
percentage required for the quality control check from the quality
control objectives file, the complete column shows the
calculated completeness taken from the input data, and the
met column shows if the standard was met by comparing if
complete is greater than or equal to
standard.
