Well, I guess when I read that "require is designed for use inside other functions..." I wasn't sure if that meant there might be times when it would be better to use library when not inside other functions. But maybe it was more generally a question about style, prompted by a post responding to the common confusion between the terms 'package' and 'library' amongst those new to R. To me, it always seemed more natural type require(my.package) than library(my.package). I just wanted to make sure I wasn't missing something that might make me regret that choice. Dan Daniel J.
