Hi, There are lots of ways to do it in base R, but a long time ago I got frustrated and wrote a crosstab function that did exactly what I wanted:
library(ecodist) mydata <- data.frame(var1=c(0,0,1,1),var2=c(0,1,0,1),freq=c(11,12,13,14)) crosstab(var1, var2, freq, data=mydata) 0 1 0 11 12 1 13 14 Sarah On Thu, Aug 13, 2015 at 5:30 AM, Dean1 <web13s...@yahoo.co.uk> wrote: > Hi all, > > I've had a few years experience with R, which is why this is so frustrating, > my problem seems so simple but I can't find a solution. > > I have a data frame in the following form: > > data.frame(var1=c(0,0,1,1),var2=c(0,1,0,1),freq=c(11,12,13,14)) > > How do I create a crosstab with frequencies? > 0 1 > 0: 11 12 > 1: 13 14 > > -- Sarah Goslee http://www.functionaldiversity.org ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
