Kieran Healy’s Baby Boom Data Visualization Poster

Together we took a look at this poster from Kieran Healy and the code from the repository.

The example was instructive on a few points:

• We thought it was neat how Kieran used the legend to create a title.
• We saw how he used cowplot::plot_grid and/or the patchwork package to construct the graphic with multiple panels.
• Seeing how png() and pdf() can be used, similar to ggsave(), to save plots was useful — especially for non-ggplot2 visualizations.
• We had to do a little bit of debugging, figuring out that we needed to use scale_x_yearmonth() instead of scale_x_date() and we figured that out by 1) reading the error we got in R, and 2) checking what the class/type of the column mapped onto the x aesthetic was.
