Combien de combinaisons par paires
# Given "LIST" a list of N elements, the number of unique pairwise comparisons
# among them is given by the formula:
ncomp = N(N-1)/2
# In order to operate all the pairwise comparison in R
library(RcppAlgos)
comboGeneral( LIST , m=2 ). #m = 2 mean PAIRWISE comparison
#To operate multiple comparisons (among 3 or mode elements) just increase m
