Hello Petr, Your solution works well with my example. But with the function I want to use (which calls another functions), I still have errors. I have to work on it again (but only on monday).
Again thank you, Ptit Bleu. PS : I have access to all the functions but I don't want to modify all of them because I just need to correct an error I discovered in already-treated data (not sure I'm clear ...). -- View this message in context: http://r.789695.n4.nabble.com/Still-confused-with-lapply-tp3050414p3050573.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
