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:

library(sp)
library(maptools)
library(rgeos)
library(ggplot2)
library(ggthemes)
 
r_wkt_gist_file <- "https://gist.githubusercontent.com/hrbrmstr/07d0ccf14c2ff109f55a/raw/db274a39b8f024468f8550d7aeaabb83c576f7ef/rlogo.wkt"
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() + 
  theme(legend.position="none")
