Details (These details are for Windows: the details differ on Unix.) The definition of the ‘home’ directory is in the rw-FAQ Q2.14: it is taken from the R _USER environment variable when path.expand is first called in a session.. The ‘path names’ need not exist nor be valid path names but prior to R 3.4.0 they needed to be representable in the session encoding.
In contrast base::path.expand() first checks for R_USER then HOME, which in the default configuration of R on Windows are both set to the user’s document directory, e.g. C:\Users\username\Documents. base::path.expand() also does not support ~otheruser syntax on Windows, whereas path_expand() does support this syntax on all systems.
Details On Unix – alikes: On most builds of R a leading ~user will expand to the home directory of user (since R 4.1.0 also without readline in use).. There are possibly different concepts of ‘home directory’: that usually used is the setting of the environment variable HOME.. The ‘path names’ need not exist nor be valid path names but they do need to be representable in the session …
path.expand(~/foo) Return Values: A character vector of possibly expanded path names: where the home directory is unknown or none is specified the path is returned unchanged. Details: (These details are for Windows: the details differ on Unix.) The definition of the ‘home’ directory is in the ‘ rw-FAQ ’ Q2.14: it is taken from the R _USER environment variable when path.expand.
path.expand {base} R Documentation: Expand File Paths Description. Expand a path name, for example by replacing a leading tilde by the user’s home directory (if defined on that platform). Usage path.expand(path) Arguments. path: character vector.
path.expand : Expand File Paths Description Usage Arguments Details Value See Also Examples Description. Expand a path name, for example by replacing a leading tilde by the user’s home directory (if defined on that platform). Usage, path.expand {base} R Documentation: Expand File Paths Description. Expand a path name, for example by replacing a leading tilde by the user’s home directory (if defined on that platform). Usage path.expand (path) Arguments. path: character vector containing one.
path.expand(path) Arguments. path: character vector containing one or more path names. Details (These details are for a Unix-alike: the details differ on Windows.) On most builds of R a leading ~user will expand to the home directory of user (since R 4.1.0 also without readline in use).
Select the Shortcut tab of the dialog box, and add one the following name/value pairs to the target field. Now path.expand (~) will expand to c:myfavoritefolder or to c:usersmy name. A couple of notes. This will also change where R looks for user files such as .Rprofile, Rconsole, and user package library.
Source: R/path.R. path_expand.Rd. path_expand () performs tilde expansion on a path, replacing instances of ~ or ~user with the user’s home directory. path_home () constructs a path within the expanded users home directory, calling it with no arguments can be useful to verify what fs considers the home directory.
