Recodes a numeric vector, character vector, or factor
according to simple recode specifications.
Usage
recode(var, recodes, as.factor.result)
Arguments
var
numeric vector, character vector, or factor.
recodes
character string of recode specifications:
see below.
as.factor.result
return a factor; default is TRUE if
var is a factor, FALSE otherwise.
Value
a recoded vector of the same length as var; if var is a factor,
then so is the result.
Details
Recode specifications appear in a character vector, separated by
semicolons (see the examples below), of the form input=output.
If an input value satisfies more than one specification,
then the first (from left to right) applies.
If no specification is satisfied, then the input value is carried
over to the result. NA is allowed on input and output.
Several recode specifications are supported:
[object Object],[object Object],[object Object],[object Object]
If all of the output values are numeric, and if as.factor.result is
FALSE, then a numeric result is returned.
