Hello,
Try the following.
names(seba)[grep("numbers", names(seba))] <- "b"
names(seba)[grep("constant", names(seba))] <- "c"
names(seba)
Hope this helps,
Rui Barradas

I have a data. frame to which you want to change the names to some of their
columns.
For example:
seba <- data.frame ('constant' = 3, 'numbers' = 1: 10, 'letters' = LETTERS
[1:10], otros = 2:11)
List their names:
names (Seba)
[1] "constant" "numbers" "letters"
I want to rename c the column called constant and b the column
called numbers.
I do not know in which order appear names.
How could do it?
Thanks in advance,
Sebastian.
