Counting Sentences in Text using R and strcount()
R
if (!require(stringr)) { install.packages("stringr") library(stringr)}text <- "This is R program for counting number of sentences in text. This program is for GFG article .And it is using stringr package for counting. And is it working ?"sentence_pattern <- "[.!?]"num_sentences <- str_count(text, sentence_pattern)cat("Number of sentences using stringr :", num_sentences, "\n") |
Output:
Number of sentences using stringr : 4
- First we install the stringr package if it is not installed and store text similarly as above in text variable.
- Then we store our regular expression in sentence_pattern variable .
- str_count() to count sentences by matching text on regular expression .
Finally we will display the sentence count using cat. Here in text there are four sentences in total 3 ending with full stop(.) and one ending with question mark(?) .Hence the output is 4
