r2dii-plot 0.2.0 is now on CRAN. This is a minor release with new features, enhancements and bug fixes. This post focuses on the new features. For everything else see the changelog.

You can install r2dii.plot from CRAN with:

install.packages("r2dii.plot")

And you can use it with library(). Here we’ll also use the ggplot2 package.

library(ggplot2, warn.conflicts = FALSE)
library(r2dii.plot)

New styling functions

A new family of functions help you apply 2DII colour palettes to any plot.

Note this plot uses data and functions from the ggplot2 package exclusively.

p <- ggplot(mpg) + geom_point(aes(displ, hwy, color = class))
p

You can now use r2dii.plot to apply 2DII’s colour scale with:

p + scale_colour_r2dii()

To discover other functions in the “2dii scale” family run ?scale_colour_r2dii() and navigate to the section “See also”.

New arguments to plot_*()

The plot_*() functions gained new arguments to replicate features of the qplot_*() functions.

For example, compare these two plots. Note the shorter (5 years) time span and nicer legend labels in the plot created with qplot_*().

data <- subset(sda, sector == "cement")

qplot_emission_intensity(data)

plot_emission_intensity(data)

You can now replicate those features of qplot_*() with the new arguments span_5yr and convert_label:

plot_emission_intensity(data, span_5yr = TRUE, convert_label = to_title)
