get_difference() returns difference between two smooths.
plot.tidygam.diff method to plot difference smooth.
Data gest and struct.
separate and sep_by arguments in predict_gam() allow the user to separate variables in the model that were created with interaction().
Vignette get-started.Rmd.
Error when predicting bivariate smooths (s/te/ti(), fs/re basis functions) where only the first variable was returned internally.
Error when plotting difference smooth with no significant difference (closes #5).
Error where get_difference() did not work when excluding random smooths (closes #8).
First minor release of the package.
Added a NEWS.md file to track changes to the package.
