Updated the sequential colour palette to add two new shades (darkest-blue and lightest-blue).
This means that the sequential palette can now be used to represent five categories, such as deprivation quintiles.
Renamed na_colour argument of scale_colour_continuous_af and scale_fill_continuous_af to na.value. This was necessary to enable use_afcharts to work with ggplot2 v4.0.1. Added na.value argument to scale_colour_discrete_af and scale_fill_discrete_af.
use_afcharts gains a reset argument to turn off analysis function styling of charts.
theme_af now uses theme options set by earlier calls of use_afcharts by default. #51
Set the main colour palettes to categorical. The Scale_*_discrete_af functions now use the 6 colour cateogrical palette by default, rather than the 4 colour.
Added af_dark_blue, af_orange and af_grey to give easier access to the hex codes of these colours.
Added arguments axis_text and axis_title to function theme_af to set
whether to show axis titles and labels.
Added argument legend_title to function theme_af to set whether to show
legend titles.
The legend argument of theme_af now accepts a legend justification e.g. 'top-right', 'left-centre' #47
Fixed bug which prevented some functions from working if called directly without attaching the package.
Fixed bug in use_afcharts when passing args to theme_af.
scale_colour_discrete_af and scale_fill_discrete_af now inform rather than warn when the main2 colour palette is used instead of main if only two colours are required.
First release of package based on sgplot.
