function (dfs, ...)
     if (length(dfs) == 2) {
         merge(dfs[[1]], dfs[[2]], all = TRUE, sort = FALSE, ...)
     else {
         merge(dfs[[1]], Recall(dfs[-1]), all = TRUE, sort = FALSE,

I do not understand how the Recall part of this function works.  Could 
somebody explain this to me?
many thanks,

Let's not spend our time and resources thinking about things that are so 
little or so large that all they really do for us is puff us up and make 
us feel like gods.  We are mammals, and have not exhausted the annoying 
little problems of being mammals.
