Error in CladeByTrait

[susyelo]

When I use the function an error appears as:

Error in as.vector(x, "character") : cannot coerce type 'closure' to vector of type 'character'

When I debugged the function it looks like when trying to write the "clades_write" data frame at the end of the function, the "area" object does not exist and in my case since I've got the raster package it tries to use the function raster::area instead.
