Arguments

gl: A geolayer object.
variables: A tibble object.
keep_all_variables_na: A boolean, keep rows with all variables NA.

When we set the variables layer, after filtering it, the data layer is also filtered keeping only the variables from the variables layer.

By default, rows that are NA for all variables are eliminated.
