[Rd] Question about writing portable packages

[Guillermo.Vinue at uv.es]

Dear Kevin, Berwin and Gabriel,

Thank you very much for your detailed and clear answers. 

According to your comments, in a few days I will submit my package to CRAN.

I would also like to take this opportunity to thank all the R-devel list
for being a wonderful place to discuss and clarify doubts about R.

Best wishes,

Guillermo
