Is there any R package to create the generalized box plot as mentioned in the research paper of (Bruffaerts, et al., 2014)

Question

I have a highly skewed and heavy tailed data. For this reason, instead of using the adjusted boxplot in R (which accounts only for the skewness of the data and not the underlying heaviness of the tail), I wanted to use the generalized boxplot since it accounts for both skewness and heaviness of the tail.

I am unable to try the generalized boxplot since I could not find its R package (if any).
