[R] cannot dyn.load dll from path

[Adrian Dragulescu]

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?

Thank you,
Adrian
