Changelog

Updates because of ggplot2 3.0.0

Add global options for scale_continuous_colour() and ggplot2.continuous.fill() to set the palettes to “gradient” instead of “viridis”
Add scale_fill_ordinal() and scale_colour_ordinal() because ordered factors now have different scale functions.

All syntax that included “urban” has been switched to “urbn”. This will be the default for any R packages made at the Urban Institute.
colors.R contains eleven palette_urbn_* vectors. More information is available in the Urban Institute Data Visualization Style Guide.
