Description Usage Arguments Value See Also Examples

Read multiple CSV files from a directory (folder)

read_dir_csv(
  path = ".",
  ...,
  all = F,
  recurse = F,
  strict_csv_ext = T,
  regexp = ".",
  invert = F,
  ignore.case = F,
  perl = F,
  fixed = F,
  snake_case = F
)

`path`	Character: Path to desired directory which contain file, default is "." working directory. (passed to `fs::dir_ls()`)
`...`	Argument to pass to `readr::read_csv()`
`all`	If `TRUE` hidden files are also returned. (passed to `fs::dir_ls()`)
`recurse`	If `TRUE` read recursively in sub-directory, if a positive number the number of levels to recurse. (passed to `fs::dir_ls()`)
`strict_csv_ext`	If `TRUE` (default): Strictly read only files, which has files name ending with .csv
`regexp`	Character: Specify a regular expression to read from file names (passed to `grep()`) . If you want to match file names other than `.csv`, turn `strict_csv_ext = FALSE`.
`invert`	Logical: If `TRUE` read from file that file names do not match `regexp`.(passed to `grep()`)
`ignore.case`	If FALSE, the regular expression matching is case sensitive and if `TRUE`, case is ignored during matching.(passed to `grep()`)
`perl`	Logical: Should Perl-compatible regexps be used? (passed to `grep()`)
`fixed`	Logical: If `TRUE`, pattern is a string to be matched as is. Overrides all conflicting arguments.
`snake_case`	If `TRUE`: Convert data frame names to snake_case_format. (require `snakecase` package)
