R help - Mar 2013 - Word Frequency for each row

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.

A "aa" "aa" "cc"

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

I think the qdap package's termco (termo count) function will do what you
want. Read the specifics as spacing around the word matters.
? ??


library(qdap); ? ? ??
termco(DATA$state, 1:nrow(DATA), c("it"))
? ??
