Cannot run any ggsubplot examples - r

Question

I am trying to run the example from the geom_subplot help page from the ggsubplot package.
library(ggplot2)
devtools::install_github('ggsubplot', 'garrettgman')
library(ggsubplot)
ggplot(nasa) +
geom_subplot(aes(long, lat, group = id,
subplot = geom_point(aes(surftemp, temperature), size = 1/4))) +
coord_map()
And I get the following error:
Error in layout_base(data, vars, drop = drop) :
At least one layer must contain all variables used for facetting
This same error occurs with with every ggsubplot example I've tried to run so far. I've tried with both the CRAN and github version of ggsubplot. I would bet this is an incompatibility with the newest version of ggplot2 but I don't know enough about ggplot development to diagnose it myself.

It seems that package ggsubplot no longer is maintained.
Message on CRAN (as of 2016-12-23):
Package ‘ggsubplot’ was removed from the CRAN repository.
