[R] count number of stop words in R

[Florian Schwendinger]

If you just want to count the stopwords you cloud do something like,

library(slam)
library(tm)

your_string <- "Mhm . Alright . There's um a young boy that's getting a cookie jar . And it he's uh in bad shape because uh the thing is falling over . And in the picture the mother is washing dishes and doesn't see it . And so is the the water is overflowing in the sink . And the dishes might get falled over if you don't fell fall over there there if you don't get it . And it there it's a picture of a kitchen window . And the curtains are very uh distinct . But the water is still flowing ."
corp <- Corpus(VectorSource(your_string))

stopwords("en")

cntrl <- list(tolower=TRUE, stopwords = NULL,
              removePunctuation = FALSE, removeNumbers = TRUE, 
              stemming = FALSE, wordLengths = c(0, Inf))


dtm <- DocumentTermMatrix(corp, cntrl)

col_sums(dtm[, which(colnames(dtm) %in% stopwords("en"))])



Best,
Florian

You can use regular expressions.

?regex and/or the stringr package are good places to start. Of
course, you have to define "stop words."


Cheers,
