Hi all R users,last time i asked about interfacing with C, well my function worked very good, but today i was using again the same function but it didn't work also the same warning with un.load() is appearing once everytime so i am obliged to put the extension .dll.I am working with Windows XP with only one same shared library containing all packages and functions in .C extension and .R extension, does this cause me all these unusual problems so that once i get the right answer from R and a lot the wrong error?Thx Ramzi
