Details

recode changes the values of variables including categorical variables according to the rules specified below.

In case of factor, recode first converts the vector into character, recodes and then revert back to factor.

If data is specified, it returns the whole dataframe with recoded variables.

Sample Inputs for conversion:

Old.value to New.value

Examples

# NOT RUN {
## use infert data
data(infert)

## tabulate induced to check values
tab(infert, induced)

## recode induced: 1 and 2 into 1
infert.new <- recode(infert, induced, c(1, 2), 1)

## tabulate to check
tab(infert.new, induced)

# }
