Convert file path to directory path

Source: R/args.R

Takes a file path and converts it to its directory path by dropping the file name and extension. If flpth is already a directory path, the argument will be returned unchanged. If nothing is provided, nothing is returned (i.e. character(0)).

Arguments

flpth

File path for which directory path will be returned.

Value

Character

Examples

library(outsider.base)
# get the parent directory from a filepath
drpth <- tempdir()
flpth <- file.path(drpth, 'testfile')
file.create(flpth)

#> [1] TRUE
(dirpath_get(flpth = flpth) == drpth)

#> [1] FALSE
(dirpath_get(flpth = drpth) == drpth)

#> [1] TRUE
file.remove(flpth)

#> [1] TRUE
