Return or remove variables or observations that are completely missing
These functions check which rows or columns of a data frame completely contain missing values, i.e. which observations or variables completely have missing values, and either 1) returns their indices; or 2) removes them from the data frame.
empty_cols(x) empty_rows(x) remove_empty_cols(x) remove_empty_rows(x)

A data frame. |
For empty_cols and empty_rows, a numeric (named) vector
with row or column indices of those variables that completely have
missing values.
For remove_empty_cols and remove_empty_rows, a
data frame with "empty" columns or rows removed.

b = c(1, NA, 3, NA , 5),
c = c(NA, NA, NA, NA, NA),
