Hello every one I'm not very familiar with drawing figures in R so maybe my question is too basic:

I have 3 groups of AF distribution each containing 2 distributions.

let's call them group1_1$AF , group1_2$AF , group2_1$AF , group2_2$AF , group3_1$AF , group3_2$AF

the point is that none of these AF distributions have the same length.

I want to draw a grouped box plot of AF distributions for group1 , group2 , group3 so that each group has two box plots of sub-groups like :group1_1$AF , group1_2$AF box plots together for group1

and group2_1$AF , group2_2$AF for group2
