After I updated my R to 3.6, I keep getting the following error when installing the package. Any idea how could I solve this?

Hi Antony, thanks for reporting.

I think the issue should be fixed now, it was reproducible with R v3.6 on Windows and Ubuntu). For posterity, it seems like R v3.6 doesn't like numeric vectors on the 'prototype' part of an S4 class definition. That seems silly to me, but is easy enough to solve in this case.

Anyways, the master branch has been updated so go ahead and try your install again. And if it works feel free to close the issue ;-).
