createLink {R.utils} | R Documentation |
Creates a link to a file or a directory
Description
Creates a link to a file or a directory. This method tries to create a link to a file/directory on the file system, e.g. a symbolic link and Windows Shortcut links. It depends on operating and file system (and argument settings), which type of link is finally created, but all this is hidden internally so that links can be created the same way regardless of system.
Usage
## Default S3 method:
createLink(link=".", target, skip=!overwrite, overwrite=FALSE,
methods=getOption("createLink/args/methods", c("unix-symlink", "windows-ntfs-symlink",
"windows-shortcut")), ...)
Arguments

is returned.
Required privileges on Windows
In order for method="unix-symlink"
(utilizing
file.symlink()
