Hi list, As I am trying to make a package myself, I met the error in R CMD check, checking examples part, as it always tells me that "Error: couldn't find function "RA"", but I know that function RA is there. And if I run those examples myself, I don't have any problem. This problem was not there before, I don't remember what I changed, but just wouldn't change back. Any help is highly appreciated!

Hi Fangxin, Is RA() a function in your package or one that is part of another package? If the latter, then your problem is very likely to be that you need to require() the package before using it. You can investigate further by adding some print() statements to the example that errors out. Helpful things to see would be what's in the current environment (ls()) and what packages are attached (search()). Also, when you try to reproduce the error in the example, you should try loading the version of your package that R CMD check installs into FOO.Rcheck (if your package is named FOO). You can use library() with lib.loc arg to achieve this. + seth
