Frequencies for a list of vectors
Hello, Maybe something like table(unlist(lapply(HTNlist, paste, collapse = ''))) (Untested, it's a bad idea not to use ?dput to give a data example.) Use dput(head(HTNlist)) # paste the output of this in a mail Hope this helps, Rui Barradas Em 05-08-2014 18:39, Marie-Pierre Sylvestre escreveu:
Dear R users, I have a list of vectors (list is called HTNlist). Each vector is of length 1 to 4 and takes only 0 and 1 as values. E.g. head(HTNlist) $`30008` [1] 1 0 1 0 $`60008` [1] 0 0 1 0 $`90008` [1] 0 0 1 0 $`100007` [1] 1 $`130001` [1] 0 1 $`130007` [1] 1 0 1 0 I would like to obtain a frequency table for the elements of the list. I want to know how many of '1 0 0' I have in the list, how many '1 0 1 0' etc. Can you please help? Thank you in advance, MP [[alternative HTML version deleted]]
