Sorry for not mentioning that, but variables sometimes have different
names.  I am looking for something like this:

loadIntoList <- function(file) {
  load(file)
  v <- list()
  ## for each variable name 'i' in ls(), assign 
  ## v$i <- i
  ## but I don't know how to write this...  I need help in that.
}

Professor Ripley mentioned save/readRDS, I have looked into that but I
need the variable names too.

Thanks,

Tamas
