recode_to: add layer to current recoding

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

Description

add layer to current recoding

Usage

recode_to(.data, 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 = NULL, otherwise.to = NA, skipped.to = NA, na.to = NA,
  questionnaire = NULL, source = NULL)

Arguments

.data	the ongoing recoding obejct, see new_recoding()
to	the value to set the new composition to if the condition is fulfilled
where	an R expression that will be evaluated in the namespace of the data (see example)
otherwise.to	an alternative value to be used if the condition is not fulfilled, the source is not NA and not skipped
skipped.to	an alternative value to be used if the source is NA because the question was skipped (requires to also supply the 'questionnaire' parameter)
na.to	an alternative value to be used if the source is NA but not skipped (and the condition is was not fulfilled)
source	you can set or change the source variable used; this will _continue_ to recode to the same target variable, and will continue to overwrite previously fulfilled conditions.
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...

Value

the updated recoding

Examples

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

df %>%
  new_recoding("new_variable_name",a) %>%
  recode_to("less than 50" ,where.num.smaller = 50) %>%
  recode_to("more or equal 50", where.num.larger.equal = 50) %>%
  recode_to("(size not important = b equals 'd')",where.selected.exactly = "d",source = b) %>%
  end_recoding()


df %>%
  new_recoding("target_var") %>%
  recode_to(5,where = a > 3 & (b %in% letters[1:3])) %>%
  end_recoding
