It doesn't work even if I set it with \\. My path has a mixture of \\ and
/ and other entries work fine.
if (file.exists("C:/Temp/XML.dll")) {
Sys.setenv(path = paste("C:\\Temp;C:/Temp;", Sys.getenv("path"), sep=""))
dyn.load("XML.dll") # doesn't find it!
}
Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared object '//nas-msw-20/adrian/My Documents/XML.dll':
LoadLibrary failure: The specified module could not be found.
My home folder is on a network drive.
Thank you,

Hello,
I'm on Windows, and according to the documentation R searches along the
search path when looking for dll's for dyn.load.
For illustration, I've copied the XML.dll from package XML in the C:/Temp
folder
if (file.exists("C:/Temp/XML.dll")) {
Sys.setenv(path = paste("C:/Temp;", Sys.getenv("path"), sep=""))
dyn.load("XML.dll") # doesn't find it!
}
head(strsplit(Sys.getenv("path"), ";")[[1]]) # C:/Temp is there
dyn.load("C:/Temp/XML.dll") # works fine
Am I misreading the documentation?
I believe that search is done by Windows, and different versions are very
inconsistent about search order. However, one thing I would guess is that
recent versions would require backslashes rather than forward slashes in
PATH. When R gets a path, it generally translates the slashes, but if you're
relying on Windows to do it, you're stuck with what they decide to do.
