Issues with next version of ggplot2

[thomasp85]

Hi

We are preparing the next release of ggplot2 and ours tests shows some issues with sdmApp. Specifically we have changed the behaviour of non-sf layers in coord_sf() so they are now interpreted as longitude and latitude coordinates instead of whatever crs the coordinate system ends up using. To get back the old behaviour you need to set default_crs = NULL in coord_sf()

we plan to submit the next ggplot2 version to CRAN on May 31st
