Dear Prof Ripley,
Thanks for your reply.
I couldn't find anything wrong with Load() function.
It seems that myEnv is not set, as myEnv <- as.environment(match(fullName, search())) does not return a valid value.
Also, when I commented the load(dataFile, myEnv) line, the rest of .First.lib code does not work (no function is loaded, e.g. when I input the function in the package, it doesn't recognise it)
Any suggestions?
Zhesi.

Looks like you have your own version of a load() function around. Try ?conflicts to see what you may have masked.

Dear all,
I just found that some of the packages are not able to load any more, after I installed R2.0.1 in my Mac, it even affects my old R1.8 installs.
It gives me errors when I load packages that contains "myEnv" settings. such as: RMySQL, DBI, Rggobi, etc. But others that does not require "myENV" is all right, like tcltk that only calls the c functions.
The errors are like: Error in load(dataFile, myEnv) : unused argument(s) ( ...) Error in library(DBI) : .First.lib failed for 'DBI'
I had a look at the package file that contains .First.lib, fullName <- paste("package", pkgname, sep=":") myEnv <- as.environment(match(fullName, search())) dataFile <- file.path(libname, pkgname, "R", "all.rda") rm(.First.lib, envir = myEnv) load(dataFile, myEnv)
I found that myEnv is not set. as the package can not be matched in search(). If I comment the line load(dataFile, myEnv), then the package is loaded without errors but there no functions is loaded at all.
It probably is something trivial. Can some one help, please?
