Plot the new SVG R logo with ggplot2

High resolution and SVG versions of the new R logo are finally available.

I converted the SVG to WKT (file here) which means we can use it like we would a shapefile in R. That includes plotting!

Here’s a short example of how to read that WKT and plot the logo using ggplot2:

r_wkt_gist_file <- ""
if (!file.exists("rlogo.wkt")) download.file(r_wkt_gist_file, "rlogo.wkt")
rlogo <- readWKT(paste0(readLines("rlogo.wkt", warn=FALSE)))
rlogo_shp <- SpatialPolygonsDataFrame(rlogo, data.frame(poly=c("halo", "r")))
rlogo_poly <- fortify(rlogo_shp, region="poly")
ggplot(rlogo_poly) + 
  geom_polygon(aes(x=long, y=lat, group=id, fill=id)) + 
  scale_fill_manual(values=c(halo="#b8babf", r="#1e63b5")) +
  coord_equal() + 
  theme_map() +
