naming vectors/ matrices in R
This is probably what you want mydf<-as.data.frame(matrix(1:60,10)) for (i in (1:dim(mydf)[2])) assign(letters[i],mydf[,i]) I would not, however, recommend it. It really does not produce very readable code.

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 It thinks I am trying to replace the first element of e with the first column of A. is there any other way in which I can achieve this? Thanks in advance
