Re: [R] Reshape dataframe according to ordered variables
Hello Duarte, It seems that order is what you are looking for : df - df[order(df$id, df$ord), ] Regards, François -Message d'origine- De : r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] De la part de Duarte Viana Envoyé : jeudi 18 mars 2010 16:27 À : r-help Objet : [R] Reshape dataframe according to ordered variables Dear all, I am still a R apprentice... Apologies for the basic question. I am trying to reshape a dataframe based on the order of two variables (a character variable and a numerical variable). To simplify it, consider the following dataframe df-data.frame(id=c(b,b,a,a,a),ord=c(2,1,1,3,2)) id ord 1 b 2 2 b 1 3 a 1 4 a 3 5 a 2 I want to reshape it such that it results in this dataframe (id alphabetically ordered and ranked according to the ord order) df1-data.frame(id=c(a,a,a,b,b),ord=c(1,2,3,1,2)) id ord 1 a 1 2 a 2 3 a 3 4 b 1 5 b 2 Thanks in advance, Duarte Viana __ 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. __ 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.
