The actually process is REALLY complicate, I just gave a simple example for the list.
I have a lot of steps to process the data before I get a final "score". (nested loops, conditional statements, etc.) Right now, I'm just printing the scores to the screen. I'd like to accumulate them in some kind of data structure so I can either write them to disk or graph them. -N On 8/26/09 12:27 PM, Erik Iverson wrote: > How about ?append, but R is vectorized, so why not just > > result_list<- 2*item^2 , or for more complicated tasks, the > apply/sapply/lapply/mapply family of functions? > > In general, the "for" loop construct can be avoided so you don't have to > think about messy indexing.
