Hi, I am not sure why ?rename() is not working. a <- list(a = 1, b = 2, c = 3) rename(a, c(b = "a", c = "b", a="c")) A.K.

I want to change all 56 headings in a single command, but 'names' allows me to change only one at a time. In Hadley's 2007 article on reshape in the Journal of Statistical Software he mentions a 'rename' function, but I cannot find that. Is there a way to change all data frame column headings in a single command?
