The codes here seem outdated for ggplot2: 2.0.0

Try my package zmisc: devtools:install_github("jerryzhujian9/ezmisc")

After you install it, you will be able to run:

df = mtcars
df$model = rownames(mtcars)

ez.radarmap(df, "model", stats="mean", lwd=1, angle=0, fontsize=0.6, facet=T, facetfontsize=1, color=id, linetype=NULL)
ez.radarmap(df, "model", stats="none", lwd=1, angle=0, fontsize=1.5, facet=F, facetfontsize=1, color=id, linetype=NULL)

if you are curious about what's inside, see my codes at github:
