Hello,
I'm not sure I understand, but see if the following is an example of
counting occurences of a word in each row.
set.seed(1855)
x <- matrix(sample(LETTERS[1:5], 400, replace = TRUE), ncol = 4)
word <- "A"
where <- apply(x, 1, function(.x) grep(word, .x))
sapply(where, length) # count them
Hope this helps,
Rui Barradas

Hi All,
I am wondering if there is any examples where you can count your
interested "word" in each row. For an example if you have data with *'ID*'
and '*write-up*' for 100 rows, how would I calculate the word frequency for
each row ?
Thank you for all your time.
