Dear Spencer,
In addition to the approaches already suggested, there is the recode()
function in the car package.

John

Hi All,
I'm relatively new to R. I have a variable, "internet use," which
ranges from "Almost everyday, "Several times a week," "Several times
a month," "Seldom," "Never," and "Don't know." I want to recode
this data into a new variable, say "use.internet," such that I have
a dichotomous variable indicating simply whether or not they have
access to the internet. Hence, I want to make "Never" and "Don't
know" equal to 0, everything else 1. I thought about doing an
if...then statement, but am not sure how to do this in R. This is
easy to do in SPSS.
A sample of the existing array is the following:
Seldom Several times a week
Several times a month
Never
Never Never Seldom
Several times a week
Never Never Almost everyday Never
And the ideal new variable:
1
1
1
0
0
0
1
1
0
0
1
0
Any help would be great!
