Dear R People

I have a simple list question, please:

I have vectors x.1, x.2,...x.n (each of different lengths) and I would
like to combine them into a list.

However, I'm sure that there is a better way to do this than to type
in x <- list(x.1,x.2,x.3,...)


Is there a better way to do this, please?  I was thinking about
possibly using grep?

If I understand your question correctly --- always a dubious assumption ---
you could do:

   n <- <however many vectors you have>
   xlist <- lapply(1:n,function(n){get(paste("x",n,sep="."))})

Does that accomplish your goal?

   cheers,
