I want to create side-by-side maps of similar attribute data in two
different cities using a single legend.
To simply display side-by-side census block group boundary
(non-thematic) maps for Minneapolis & Cleveland I do the following:
I can display a single thematic map for a city using spplot as follows:
But, calling the function again for Cleveland just overwrites the
window. I am unsure how to use spplot's layout tools with two different
geographies. Most examples use a single geography and multiple attribute
columns. Alternatively, is there a way to use "par" together with spplot
to allow for multiple spplot calls?
