[R] running custom functions in Snow clusters

When running a function in parallel using for example the clusterCall function in Snow is it possible to call other user-written functions from each cluster? I get an error when I try to do this. I tried to source the function on each cluster using the clusterEvalQ function but this doesn't seem to work. This is more of an aesthetic problem than an actual one as obviously I can write a group of functions as one function and call this with clusterCall.

Thanks,
