gghighlight 0.3.3

gghighlight 0.3.2

gghighlight() now accepts n() so that you can highlight based on the number of rows within each group (#154).
gghighlight() now preserves colour or fill when explicit NULL is specified on unhighlighted_params (i.e. unhighlighted_params = list(colour = NULL)) (#152).
Fix a longstanding bug of wrong calculation when the data has the same name of columns as aesthetics, e.g. x (#168).

gghighlight_point() and gghighlight_line(), deprecated in gghighlight 0.1.0, are now defunct (#132).

gghighlight() gets a new argument unhighlighted_params, which accepts a list of parameters for the unhighlighted layer (e.g. colour, fill, shape, and size). Accordingly, unhighlighted_colour is deprecated (#76).
gghighlight() gets a new argument keep_scales to choose whether to keep the original scale with the shadowed data (#72).
gghighlight() gets a new (experimental) argument calculate_per_facet to choose whether to calculate highlighting per facet or not (#14).

If the mapping has group, use it as grouping variable, which is consistent with the logic of ggplot2 (#77).
gghighlight() now ignores if the calculation fails over some layers. This is useful to combine with such layers as annotate() (#78).
gghighlight() now allows to highlight 0-layer plots, which means just filtering the plot data (#81).
gghighlight() now ignores NAs in numeric predicates (#86).

Add gghighlight(), which replaces the current gghighlight_line() and gghighlight_point(); these functions are now deprecated.
Add a introductory vignette.
