file.path

R Base 3.6.2

Construct the path to a file from components in a platform-independent way.

Syntax

file.path(&#8230;, fsep = .Platform$file.sep)

Arguments

Parameter	Description
`…`	character vectors.
`fsep`	the path separator to use.

Return Value

A character vector of the arguments concatenated term-by-term and separated by fsep if all arguments have positive length; otherwise, an empty character vector (unlike paste).

Details

The implementation is designed to be fast (faster than paste) as this function is used extensively in R itself. It can also be used for environment paths such as PATH and R_LIBS with fsep = .Platform$path.sep. Trailing path separators are invalid for Windows file paths apart from / and d:/ (although some functions/utilities do accept them), so a trailing / or \ is removed.
