getRelativeURL: Compute name of URL relative to a base URL

Description

This function is a convenience function for computing the fullly qualified URI of a document relative to a base URL. It handles the case where the document is already fully qualified and so ignores the base URL or, alternatively, is a relative document name and so prepends the base URL. It does not (yet) try to be clever by collapsing relative directories such as "..".

Usage

getRelativeURL(u, baseURL, sep = "/")

Arguments

u

the location of the target document whose fully qualified URI is to be determined.

baseURL

the base URL relative to which the value of u should be interpreted.

sep

the separator to use to separate elements of the path. For external URLs (e.g. accessed via HTTP, HTTPS, FTP), / should be used. For local files on Windows machines one might use .Platform$file.sep, but this is incorrect unless one

Value

• A character string giving the fully qualified URI for u.
