Assign a column of a data.frame with string name in R

Answer 1

Maybe you want this:

R> A <- data.frame(a=c(1,2,3), b=c(3,6,2))
R> colnames(A) <- paste("Names", 1:ncol(A), sep="")
R> A
  Names1 Names2
1      1      3
2      2      6
3      3      2

but as Tyler said in the comment, it is not entirely clear what you are asking.
