Re: [R] Problem with nested for-loop

Thanks. That helps. Using the example data you sent, I came up with this loop. See if it does the trick for you. niter <- 2 nspp <- 11 ntrees <- 22 lnbm <- matrix(NA, niter, ntrees) for(i in 1:niter) { for(j in 1:ntrees) { k <- j1data$its==i & j1data$spp==predictdata$spp[j] lnbm[i, j] <- j1dat

Re: [R] Problem with nested for-loop

It would be helpful to see what your data frames look like ... perhaps you could share the first few rows of each with us. dput(head(j1data)) dput(head(predictdata)) Jean On Mon, Mar 25, 2013 at 9:29 PM, Curtis Burkhalter < curtisburkhal...@gmail.com> wrote: > Hello, > > I'm working on a prob
