Error creating named character vectors from column names in data frame.

Hi everyone,

I was hoping someone would explain why this doesn't work.

c("a" = "b") # named character vector
class("a") # character
class("b") # character

c(names(mtcars)[1] = names(mtcars[2]) # error
class(names(mtcars)[1]) # character
class(names(mtcars)[2]) # character


Thanks,
Jorge Cimentada
