I may or may not have the most elegant solution to this problem, but if it
were me, I would probably put them all in a list and then
unique_matrix_list <- unique(list_of_matrix)
# number of unique matricies:
length(unique_matrix_list)
# count the number of each matrix,
for (m in unique_matrix_list) {
count_m <- which(list_of_matrix == m)
}
but, i havent done this myself.
see
?unique
and maybe that'll help.
