Error with facet_trelliscope when plotting sf objects with ggplot2

[juanmayorgahenao]

Does facet_trelliscope() work with ggplot2::geom_sf()? The funtion is failing on me when facet_wrap() works fine.

nc %>% select(SID74, SID79, geom) %>% gather(VAR, SID, -geom) %>% geom_sf(data = nc2, aes(fill = SID)) + facet_wrap(~ VAR)

The above works. But this fails:

nc %>% select(SID74, SID79, geom) %>% gather(VAR, SID, -geom) %>% geom_sf(data = nc2, aes(fill = SID)) + trelliscopejs::facet_trelliscope(~ VAR)

Interesting. I haven't tried it with geom_sf(). Can you send a reproducible example?
