Wrapper for recode from car to allow to recode multiple columns at once

1	recode2(x, vars = NULL, ...)

x

A dataframe.

vars

A vector of variable names or numeric indexes to select the columns to recode.

...

Arguments that are passed on to recode from car (see ?recode for more info).

`recodes`	Character string of recode specifications: see below.
`as.factor.result`	Return a factor; default is `TRUE` if the column is a factor, `FALSE` otherwise.
`as.numeric.result`	If `TRUE` (the default), and `as.factor.result` is `FALSE`, then the result will be coerced to numeric if all values in the result are numerals — i.e., represent numbers.
`levels`	An optional argument specifying the order of the levels in the returned factor; the default is to use the sort order of the level names.
`...`	More arguments passed to `recode`.

A dataframe with recoded columns.

Mark Heckmann

a <- attitude
rec <- "0:50=1; 51:70=2; 60:100=3; else=NA"
recode2(a, recodes=rec)
recode2(a, vars=1:2, recodes=rec)
recode2(a, vars=c("rating", "complaints"), recodes=rec)
