[R] Word Frequency for each row

[arun]

Hi,
You can also try:
   res2<-rowSums(x==word)

res1<-sapply(where,length)
res1[]<- sapply(res1,as.numeric)
 identical(res1,res2)
#[1] TRUE
A.K.

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
