Is there a way to convince R to create a character vector without using the quotes?

This works

ex1 <-  c("first","second")

but when I try this it doesn't

ext <- as.character(c(first,second))

it complains. I have many variables to put into character vectors so dispensing with the quotes would be useful.

Thanks

Jim
