File Extension Checks

Check whether file extension is as specified

Usage

is_txt_file(x)

is_csv_file(x)

is_excel_file(x)

is_r_file(x)

is_rdata_file(x)

is_rda_file(x)

is_rds_file(x)

is_spss_file(x)

check_ext_against(x, ext = "txt")

Arguments

x

file(s) to be tested

ext

extension to test against

Value

a logical value

Note

These only check the file extension and not the contents of the file. Checking the contents of a file might come later but would be quite a bit more involved. You can use `readr` or `readxl` (for example) to check the file contents.

Examples

# create your own file extension checks
is_word_file <- function(x){
  check_ext_against(x, ext = c("doc", "docx"))
}
is_word_file(c("blah.doc", "blah.docx", "blah.txt"))
#> [1]  TRUE  TRUE FALSE
