Apply a function to every atom in a grab tree
Examples
g <- grab_atom("point", dfr(x = c(0.2, 0.8), y = c(0.3, 0.7)))
#> Error in grab_atom("point", dfr(x = c(0.2, 0.8), y = c(0.3, 0.7))): could not find function "grab_atom"
grab_map_atoms(g, function(atom) atom)
#> Error in grab_map_atoms(g, function(atom) atom): could not find function "grab_map_atoms"
