[R] count number of stop words in R

[Elahe chalabi]

Defining data as you mentioned in your respond causes the following error:

    
Error in UseMethod("tm_map", x) : 
no applicable method for 'tm_map' applied to an object of class "character"

I can solve this error by using  Corpus(VectorSource(my string)) and the using your command but I cannot see the number of stop words in my string!

define your string as whatever object you want:
data <- "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."

Thanks for your reply. I know the command  
data <- tm_map(data, removeWords, stopwords("english"))
removes English stop words, I don't know how should I count stop words of my string:


str="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 .

You can define stop words as below.
data <- tm_map(data, removeWords, stopwords("english"))

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,
