  • Remove file extensions with str_remove_fileext()

  • Extract existing file names str_extract_fileext() (returning NA values if a string has no file extension)

Usage

str_add_fileext(string, fileext = NULL)

str_remove_fileext(string, fileext = NULL)

str_extract_fileext(string, fileext = NULL)

Arguments
