df <- df[order(df$x, df$y),] # sort df by x and y with priority to x -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] la part de Luis Ridao Cruz Envoye : vendredi 11 fevrier 2005 16:03 A : [email protected] Objet : [R] Double sort a data frame R-help, Long ago I asked how to sort a data frame according to one of the columns. But Iwas wondering ho I could "double sort" , i.e, sort according to one column and another one afterwards. It is quite easy in Excel but I am unable to implemented in R. I have searched in the R help archives and found nothing. Thank you in advance. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
