Hello together, i have a big problem, to convert a column in my data.frame to numeric. I have: 61,13 in the column and write: data$PT_DL<-as.numeric(as.character(data$PT_DL)) the result is NA, not a point seperated number. How can i change the data to an as.numeric number? Thank you for your help. Mat -- View this message in context: http://r.789695.n4.nabble.com/comma-as-a-seperator-to-numeric-tp4651090.html Sent from the R help mailing list archive at Nabble.com.
comma as a seperator to numeric

Hi Mat, You could first replace your commas with points using gsub(). Or you could import your data differently (using read.csv2() for example) See ?gsub and ?read.csv HTH, Ivan -- Ivan CALANDRA Universit? de Bourgogne UMR CNRS/uB 6282 Biog?osciences 6 Boulevard Gabriel 21000 Dijon, FRANCE +33(0)3.80.39.63.06 ivan.calandra at u-bourgogne.fr http://biogeosciences.u-bourgogne.fr/calandra Le 28/11/12 09:03, Mat a ?crit :

gsub() works perfectly, thank you very much. Mat -- View this message in context: http://r.789695.n4.nabble.com/comma-as-a-seperator-to-numeric-tp4651090p4651106.html Sent from the R help mailing list archive at Nabble.com.
