[R] Seeking help in Package development

[Uwe Ligges]

May I add that the best documentation for building packages is the 
"Writing R Extensions" that ships with the current R version. It is 
always current, precise, and not as outdated as many resources you find 
"somewhere" in the web - yes, the one cited below is outdated.
