topcode.data.Rd
this function uses topcode.var
to topcode a set of variables.
it's useful for topcoding a whole set of aggregated relational data
("how many X are you connected to?") questions in the same way.
topcode.data(survey.data, vars, max, to.na = NULL, ignore = NA)
survey.data | the dataset with the survey responses |
---|---|
vars | a vector with the names or indices of the columns in the dataframe that are to be topcoded |
max | the maximum value; all values > max are recoded to max |
to.na | a vector of values to recode to NA (this happens before topcoding) |
ignore | a vector of values to leave unchanged |
the topcoded vector
if (FALSE) { data(hh.survey) # example data included with the package example.survey <- topcode.data(example.survey, vars=known.popn.vars, max=30) }
