Convert data into nabular form by binding shade to it

Binding a shadow matrix to a regular dataframe converts it into nabular data, which makes it easier to visualise and work with missing data.

nabular(data, only_miss = FALSE, ...)

Arguments

data	a dataframe
only_miss	logical - if FALSE (default) it will bind a dataframe with all of the variables duplicated with their shadow. Setting this to TRUE will bind variables only those variables that contain missing values. See the examples for more details.
...	extra options to pass to `recode_shadow()` - a work in progress.

data with the added variable shifted and the suffix _NA


aq_nab <- nabular(airquality)
aq_s <- bind_shadow(airquality)

all.equal(aq_nab, aq_s)
#> [1] TRUE
