Hello, I have a text file with one column containing long number but stored as string. I download the file with read.table (and colClass) and the first row of this column is :
"095842087016731010" As I need to make some calculations with these numbers, I tried to convert them using as.numeric. But then I get as.numeric("095842087016731010") 95842087016731008 I understand the disappearing of the first 0 but I don't understand the substitution of the last 0 by 8. Is there a way to avoid that ? Thanks in advance, Ptit Bleu. -- View this message in context: http://r.789695.n4.nabble.com/Problem-with-long-number-from-character-to-numeric-class-tp3297121p3297121.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.
