system.file("",package") is documented to return the root of the
package
(as it did in the past). It actually returns "" (Win98, R1.3.0),
breaking
the SJava package
Omitting the first argument does work correctly and so is a workaround if
the argument is explicitly "" but not if it is the value of a
variable.

I think you were caught by R> system.file("", "eda") [1] "" but you need to do R> system.file("", package = "eda") [1] "/usr/local/lib/R/library/eda/" -k -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- 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 !)

It's the trailing slash that is the problem, and which is not as documented in the Value section. That is not a file under Windows, and so file.exists() fails. (That suprised me a bit, but one could argue it is not actually a file under Unix either: the directory file is /ext/R/1.3.0/lib/R/library/eda and that does work.) Rather than special-case system.file("",package), I think we should remove the `or \code{""}' from the documentation.
