| getRelativePath {R.utils} | R Documentation |
Gets the relative pathname relative to a directory.
## Default S3 method: getRelativePath(pathname, relativeTo=getwd(), caseSensitive=NULL, ...)
pathname |
A character string of the pathname to be converted into
an relative pathname. |
relativeTo |
A character string of the reference pathname. |
caseSensitive |
If TRUE, the comparison is case sensitive, otherwise
not. If NULL, it is decided from the relative path. |
... |
Not used. |
In case the two paths are on different file systems, for instance,
C:/foo/bar/ and D:/foo/, the method returns pathname as is.
Returns a character string of the relative pathname.
If caseSensitive == NULL, the relative path is used to decide if
the comparison should be done in a case-sensitive mode or not.
The current check is if it is a Windows path or not, that is, if
the relative path starts with a device letter, then the comparison
is non-case sensitive.
