tm_plot(use_gradient, limit_latitude_3857)
Use gradient fill using linearGradient()
Vector of two limit latitude values for maps printed in Web Mercator projection (EPSG 3857). If c(-90, 90)
the poles will be inflated too much. The Web Mercator is defines as c(-85.06, 85.06)
, but the default setting in tmap is c(-84, 84)
