system.file on Windows, / vs \\ (PR#586)

Thu, Jun 29, 2000 9:49 AM #

Under Windows, system.file() can return a path with both / and \\
characters (R 1.0.0)
eg

"C:\\PROGRA~1\\R\\rw1000/library/modreg/libs"

This is fine when passed to R functions but not when passed to eg Tcl.

Yes, but the bug is in TCL, not R!  Such paths are valid paths on Windows,
with \ being preferred, but TCL does not accept paths containing \, which I
find pretty amazing.  I am not sure it handles drives properly, either.

In a few cases / or \ is required, so you will see gsub used quite
frequently in Windows R code.
