Re: [R] for loop with global variables

Hi,

thank you for the response. What I actually want to do is pick automatically the results of the various outputs (which I have already defined as variables, e.g. output.1,output.2,etc) and insert them into a table. The list variable would be redundant since in order to create the data frame I would rather type data.frame(results=rbind(output.1,output.2,etc.)). If I had 100 outputs, this would be much work. I rather meant something like for(i in 1:100) {x=data.frame(results=rbind(output.[[i]]))}, which does not work though. It says that object "output." cannot be found.

Kind Regards
