impute_mean
impute_mean
imputes the mean for a vector. To get it to work on all
variables, use impute_mean_all
. To only impute variables
that satisfy a specific condition, use the scoped variants,
impute_below_at
, and impute_below_if
. To use _at
effectively,
you must know that _at`` affects variables selected with a character vector, or with
vars()'.
