R help - Feb 2006 - Group a dinamic number of vectors in a data.frame

Hi all,

I need to create a data.frame from a variable number of vectors.
The number of these vectors could change so I need a dinamic way to
group all in a data.frame. The number is length(abc).

e.g. vectors in my workspace

N1 <-c(1,2,3,4)
N2 <-c(1,2,3,4)
N3 <-c(1,2,3,4)
abc <-c(1,2,3)

the data.frame I want to create:

tcm <-data.frame(OneVector, TwoVector,  paste("N",1:length(abc)))

Obviously :) if I am here this approach doesn't work, so any kind of tip
is welcome.

Cheers

For example:

   lab <- paste("N", seq(along=abc), sep="")
   D <- data.frame(lapply(lab, get))
   names(D) <- lab
