simplifyPath: Simplify folder/directory paths.

In omegahat/RHTMLForms: Programmatically create R functions corresponding to Web/HTML forms.

Simplify folder/directory paths.

Description

This is a basic function that removes relative navigation within a directory path. In other words, it attempts to resolve .. and ..

Note that the function does not currently do extensive checking that the result makes sense. To truly do this and to take account of symbolic links, etc., we need to check via the operating system. We also don't worry about drive names (e.g. C:, F:) on Windows systems.

Usage

simplifyPath(path, sep = "/")

Arguments

path	the vector of path strings to simplify.
sep	the directory separator. Since this is used for URIs, we use / as the default. We could use .Platform$file.sep.

Value

A character vector with as many elements.
