Dear Alessando, I don´t know if I understood well your question, but my be you are not "losting" the precision. Try change the options(digits=10). If you want to output with "," as sepatator, try something like write.table(testground, "my_output.txt", sep=",", append=F, quote=F, row.names=F) but if you want TAB as sepatador try this: write.table(testground, "my_output.txt", sep="\t", append=F, quote=F, row.names=F) Best wishes miltinho astronauta brazil On 8/8/08, Alessandro <alessandro.montaghi@unifi.it> wrote:> > Hi All, > > > > I have 2 questions: > > 1.
