Hi Ragia, The basic method is to use "table" and examine the result:
> a<-matrix(c(3,3,4,3,6,6),nrow=2) > b<-matrix(c(3,3,4,4,6,6),nrow=2) > table(a) a 3 4 6 3 1 2 but you can get the modal value directly like this: library(prettyR) Mode(a) [1] "3" Mode(b) [1] ">1 mode" Jim On Mon, Jun 15, 2015 at 9:04 AM, Ragia Ibrahim <ragi...@hotmail.com> wrote: > Dear group, > I have the following integer object > >> a > > 3 4 6 > 3 3 6 > > how to get the most frequent value (it should be 3) > > and get nothing if no frequent one and all is equal > > 3 4 6 > 3 4 6 > Thanks in advance > Ragia > > [[alternative HTML version deleted]] > > ______________________________________________ > 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. ______________________________________________ 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.
