Examples

library(nprcgenekeepr)
ped <- nprcgenekeepr::qcPed
ped <- ped[order(ped$id), ]
genotype <- data.frame(
  id = ped$id[50 + 1:20],
  first_name = paste0("first_name", 1:20),
  second_name = paste0("second_name", 1:20),
  stringsAsFactors = FALSE
)

## checkGenotypeFile disallows dataframe with < 3 columns
tryCatch(
  {
    checkGenotypeFile(genotype[, c("id", "first_name")])
  },
  warning = function(w) {
    cat("Warning produced")
  },
  error = function(e) {
    cat("Error produced")
  }
