Recoding Data

Recodes or reverse codes a vector of scores

rescore(x, from, to = names(from), reverse = missing(from), trynumeric = TRUE)

`x`	vector of scores to be recoded.
`from`	list of old values in `x` which will be recoded according to the name of the list element, unless `to` is specified.
`to`	vector of new values to be assigned to corresponding value(s) in `from`, assuming `from` and `to` are the same length.
`reverse`	logical, with default `TRUE` when `from` is missing. If TRUE, old and new are ignored and `x` is simply reverse coded. Assumes all possible values are at least ordinal scale quantitative and observed.
`trynumeric`	logical with default `TRUE`. If `TRUE`, an attempt is made to convert values in `to` to “`numeric`”. `as.numeric(to)` must first succeed without warnings.
