Splits a vector of radiocarbon lab IDs (e.g. "OxA-1234")
into its constituent parts: the lab code ("OxA") and quasi-numeric unique
identifier ("1324"). If x contains values that don't fit the standard
format ("OxA-1234" or "OxA 4567"), by default the function will attempt
to fix these with c14_fix_lab_id() before parsing.
Arguments
- x
Vector of lab IDs, e.g.
"OxA-1234".- fix
If
TRUE(the default), attempts to fix malformed lab IDs before parsing.
Value
A data frame with two character columns: lab_code and lab_number. If x
is of length one, this is simplified to a named character vector of length 2.
Examples
c14_parse_lab_id(c("OxA-1234", "Ly 456", "RT 1234-5678"))
#> lab_code lab_number
#> 1 OxA 1234
#> 2 Ly 456
#> 3 RT 1234-5678
# By default, tries to fix malformed values of x before parsing
# Use fix = FALSE for strict parsing
c14_parse_lab_id(c("OxA 1234", "OxA_5678", "Gif/LSN-123"))
#> lab_code lab_number
#> 1 OxA 1234
#> 2 OxA 5678
#> 3 Gif/LSN 123
c14_parse_lab_id(c("OxA 1234", "OxA_5678", "Gif/LSN-123"), fix = FALSE)
#> lab_code lab_number
#> 1 OxA 1234
#> 2 OxA 5678
#> 3 Gif/LSN 123
# Single values of x are simplified to a character vector
c14_parse_lab_id("OxA 1234")
#> lab_code lab_number
#> "OxA" "1234"
