In mabafaba/composr: Compose new variables - horizontal recoding operations

Description

add layer to current composition

Usage

compose(.data, source, to, where.selected.any = NULL,
  where.selected.all = NULL, where.selected.exactly = NULL,
  where.selected.none = NULL, where.num.equal = NULL,
  where.num.smaller = NULL, where.num.smaller.equal = NULL,
  where.num.larger = NULL, where.num.larger.equal = NULL,
  where.string = NULL, otherwise.to = NA, skipped.to = NA,
  na.to = NA, questionnaire = NULL)

Arguments

.data	the composition, see new_composition()
source	the name of the source variable to compose from
to	the value to set the new composition to if the condition is fulfilled
where.selected..	: a vector of choices; setting values to 'to' where in the source variable any/all/exactly/none of the supplied choices had been selected
where.num...	: a scalar number. setting values to 'to' where the 'source' is equal / smaller / smaller or equal / larger / larger or euqal than the number supplied in where.num...
otherwise	an alternative value to be used if the condition is not fulfilled, the source is not NA and not skipped

Value

the updated composition

Examples

df<-data.frame(a=1:100,b=sample(letters[1:5],100,T))

df %>% new_composition("new_variable_name") %>%
compose("a",to = "less than 50" ,where.num.smaller = 50) %>%
compose("a",to = "more or equal 50", where.num.larger.equal = 50)
compose("b",to = "(size not important)",where.selected.exactly = "d") %>%
end_composition()
