str_give_ext: Ensure a file name has the intended extension.

Description

Say you want to ensure a name is fit to be the name of a csv file. Then, if the input doesn't end with ".csv", this function will tack ".csv" onto the end of it. This is vectorized over the first argument.

Usage

str_give_ext(string, ext, replace = FALSE)

Value

A string: the file name in your intended form.

Arguments

string

The intended file name.

ext

The intended file extension (with or without the ".").

replace

If the file has an extension already, replace it (or append the new extension name)?

Examples

str_give_ext(c("abc", "abc.csv"), "csv")
str_give_ext("abc.csv", "pdf")
str_give_ext("abc.csv", "pdf", replace = TRUE)
