Bug fix release

This release fixes a bug in the use of the select argument to draw.gam(), which was resulting in the wrong smooths being plotted.

First CRAN submission of gratia

gratia recently reached version 0.2-0 and after some last-minute teething issues related to a new release of the tibble package, gratia was submitted to CRAN.

The package is ready for public release and has been widely tested against a range of estimated models. In particular, the package is now used to support a paper that I've been involved with writing on hierarchical GAMs.
