[R] help loading files into R for koRpus analysis

like koRpus would be limited in usefulness if there were no way to get the package to do its work on a large collection of files all at once. I hope this problem will make sense to someone, and that there is a tenable solution to it. Thanks, Gordon [[alternative HTML version deleted

Never mind, I find a generic solution: require(reshape) melted<-melt(dataframe, id=c("id","f1","f2")) averaged=cast(melted,id+f1~variable,mean) which collapses away "f2", and it's easy to generalize this to collapse any factors. Thanks anyway
