Thanks for all your answers. I didn't know this limit. I finally found another way to go around this problem: luckily the 4 first figures are always the same for all these numbers. I created a new column with as.numeric(substr(df$BigNumber,5,18)). Numbers are now 14-figures long and it is now ok.
Have a nice end of day, Ptit Bleu. -- View this message in context: http://r.789695.n4.nabble.com/Problem-with-long-number-from-character-to-numeric-class-tp3297121p3297491.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.
