I need help with (hopefully) just one more thing. I have been fussing with this for quite some time and have decided just to give up and ask! I want to match a column in a matrix to a vector. I found a "which" command that I thought would be helpful as it does the following:
> g=c(1,5,3,2,7) > which(g==5) [1] 2 As the above gave which placement in the g vector corresponded to 5 (the second place), I need this command to give me which column in a matrix matches to a vector. This is just a toy example of what I am trying to do: > t=matrix(1:12,3,4) >v=c(1,2,3) >which(t[,j]==v) This does not work, and with my "real" matrices and vectors, I was getting outputs that did not make sense. These examples are more to give an idea of what I am aiming to accomplish. Thank you for all the help!! ______________________________________________ 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.
