Check ggplot layers for use of a specific geom — is_any_layer_class • spinifex

Checks if any of the layers of a ggplot contain a specific class.

is_any_layer_class(ggplot, class_nm = "GeomDensity")

Arguments

ggplot: Check the layers of this ggplot object
class_nm: The class name to check, note this differs slightly from the name of the geom function. Defaults to "GeomDensity", checking to see if geom_density was used in any of the layers.

#> [1] TRUE
is_any_layer_class(g, "GeomPoint")
