### ggradar
<https://github.com/ricardo-bion/ggradar>

ggradar allows you to build radar charts with ggplot2. This package is based on [Paul Williamson's](http://rstudio-pubs-static.s3.amazonaws.com/5795_e6e6411731bb4f1b9cc7eb49499c2082.html) code, with new aesthetics and compatibility with ggplot2 2.0.

It was inspired by [d3radaR](http://www.buildingwidgets.com/blog/2015/12/9/week-49-d3radarr), an htmlwidget built by [timelyportfolio](https://github.com/timelyportfolio).

```{r, message=FALSE,warning=FALSE, fig.width=15, fig.height=10}
# Example from https://github.com/ricardo-bion/ggradar
library(ggplot2)
library(ggradar)
suppressPackageStartupMessages(library(dplyr))
library(scales)

mtcars %>%
     add_rownames( var = "group" ) %>%
     mutate_each(funs(rescale), -group) %>%
     tail(4) %>% select(1:10) -> mtcars_radar

ggradar(mtcars_radar)

```


```{r}

knitr::kable(mtcars_radar,format="markdown")

```

## Custom fonts

This package requires the Airbnb font and the extrafont package.

```{r, eval=FALSE}

# configured to work on a Mac, change directory to Unix or Windows
download.file("https://dl.dropboxusercontent.com/u/2364714/airbnb_ttf_fonts/Circular Air-Light 3.46.45 PM.ttf", "/Library/Fonts/Circular Air-Light 3.46.45 PM.ttf", method="curl")

extrafont::font_import(pattern = 'Circular', prompt=FALSE)
```
