guess_time_only_filter function

Try at determining which are true time only variables

This is just a try at guessing data type based on data class and column names hoping for a tiny bit of naming consistency. R does not include a time-only data format natively, so the "hms" class from readr is used. This has to be converted to character class before REDCap upload.

guess_time_only_filter(
  data,
  validate = FALSE,
  sel.pos = "[Tt]i[d(me)]",
  sel.neg = "[Dd]at[eo]"
)

Arguments

• data: data set
• validate: flag to output validation data. Will output list.
• sel.pos: Positive selection regex string
• sel.neg: Negative selection regex string

Returns

character vector or list depending on validate flag.

Examples

data <- redcapcast_data
data |> guess_time_only_filter()
data |>
  guess_time_only_filter(validate = TRUE) |>
  lapply(head)
