case_match_regex_list(data, match.list, .default = NA)

Arguments

• data:

  vector

• match.list:

  list of case matches

• .default:

Examples

case_match_regex_list(
  c("test_date", "test_time", "test_tida", "test_tid"),
  list(date_dmy = "_dat[eo]$", time_hh_mm_ss = "_ti[md]e?$")
)
#> [1] "date_dmy"      "time_hh_mm_ss" NA              "time_hh_mm_ss"
