[Rd] system.file on Windows, / vs \\ (PR#586)
Under Windows, system.file() can return a path with both / and \\ characters (R 1.0.0) eg> system.file("libs",pkg="modreg")"C:\\PROGRA~1\\R\\rw1000/library/modreg/libs" This is fine when passed to R functions but not when passed to eg Tcl. -thomas -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

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. -- Brian D.
