[R] Package Building and Name Space

Hi Johannes,

Apparently the package 'strapply' does not have the namespace, so you cannot
use importFrom directive to import gsubfn() from it. In that case, I
believe, you need to rely on the "old" mechanism using require(). Apart from
that, it also seems that 'strapply' package is not even in the R search
path. Do you see it in the listing created by a call to library()?
