[R] Package Building and Name Space

[Johannes Graumann]

Hello,

I don't think package gsubfn which is supposed to provide
function 'strapply' is the culprit (just yet). The error message was that
my own new package has no name space and isn't in the search path (the
second is possibly easily explained by the fact that it's supposed to be
installed after packaging it ;0).

I'm taking this to the developer list, where it should have gone to begin
with ...

Thanks, Joh
