ggradar R Package

You can customize the typography of your radar chart using the font.radar argument. To use a custom font:

1. Download the font file to your system.
2. Install the font on your operating system.
3. Register the font in R using the extrafont package.
4. Pass the font family name to the font.radar parameter in ggradar().

ggradar can be used directly in a pipe (%>%) workflow.

# Example using a custom font 'Circular Air' in a pipe
mtcars %>% 
  as_tibble(rownames = "group") %>% 
  mutate_at(vars(-group), rescale) %>% 
  tail(4) %>% 
  select(1:10) %>% 
  ggradar(font.radar = "Circular Air")

To install ggradar, use the devtools::install_github function. Ensure you set dependencies = TRUE to install all necessary requirements.

devtools::install_github("ricardo-bion/ggradar", 
                          dependencies = TRUE)

To use ggradar, prepare a data frame where one column (e.g., group) contains the labels for the radar axes, and the remaining columns contain the numeric values. It is highly recommended to rescale your numeric values (e.g., using scales::rescale) so they fall within a consistent range (typically 0 to 1) before plotting.

library(ggradar)
library(dplyr)
library(scales)
library(tibble)

# Prepare data: convert to tibble, rescale numeric columns, and select features
mtcars_radar <- mtcars %>% 
  as_tibble(rownames = "group") %>% 
  mutate_at(vars(-group), rescale) %>% 
  tail(4) %>% 
  select(1:10)

# Generate the radar chart
ggradar(mtcars_radar)
