I am able to split my df into two like so: dataset <- trainset index <- 1:nrow(dataset) testindex <- sample(index, trunc(length(index)*30/100)) trainset <- dataset[-testindex,] testset <- dataset[testindex,-1]
So I have the index information, how could I re-combine the data using that back into a single df? I tried what I thought might work, but failed with: newdataset[testindex] = testset[testindex] object 'dataset' not found newdataset[-testindex] = trainset[-testindex] object 'dataset' not found Brian ______________________________________________ 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.
