naming vectors/ matrices in R

I would like to create a series of vectors in a loop and name them with letters. I know the command letters gives me the 26 letters of the alphabet. For example, I have a dataframe, called A, with 6 columns.
B<-length(A) C<-letters(1:B)
[1] "a" "b" "c" "d" "e" "f" I would like to extract the first letter "a", and put the first column of dataframe A in a vector called "a"
C<-e[1]
[1] "a" but when I type
e[1]=A[,1]
Warning message: In e[1] =A[, 1] : number of items to replace is not a multiple of replacement length
This is really difficult to understand. Try to make the example so that is can be pasted in R. For example, where is your dataframe A? A = data.frame(a=1:10,b=1:10) e = A[,1] e Dieter
