Apply gross range QC flag

Usage

utilASRflaggross(flag, vals, dqo)

Arguments

flag: character vector of current flag values ("pass", "suspect", or "fail").
vals: numeric vector of observed values, the same length as flag.
dqo: two-row data frame from data quality objectives for the parameter being checked, containing one row where Flag == "Fail" and one where Flag == "Suspect". Must contain numeric columns GrMin and GrMax.

Value

Updated character flag vector.

Details

Observations below GrMin or above GrMax in the "Fail" row are flagged "fail". Observations below GrMin or above GrMax in the "Suspect" row (but within the fail bounds) are flagged "suspect". NA threshold values are silently skipped.

Examples

flag <- rep("pass", 5)
vals <- c(-2, 0, 15, 26, 32)
dqo <- data.frame(
  Flag = c("Fail", "Suspect"),
  GrMin = c(-1, 0), GrMax = c(30, 25)
)
utilASRflaggross(flag, vals, dqo)
#> [1] "fail"    "pass"    "pass"    "suspect" "fail"
