Frequencies for a list of vectors
You can those vectors into character strings and pass them to table(). E.g.,
d <- list(`30008`=c(1,0,1,0), `60008`=c(0,0,1,0), `90008`=c(0,0,1,0), `100007`=1, `130001`=c(0,1), `130007`=c(1,0,1,0)) dChar <- vapply(d, FUN=function(di)paste(di, collapse=" "), FUN.VALUE="") dTable <- table(dChar) dTable
dChar
0 0 1 0 0 1 1 1 0 1 0
2 1 1 2
dTable["1 0 1 0"]
1 0 1 0
2

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
