[R] str_count counts the substring

[arun]

Hi,

May be this helps:
str1<- "Brazil is the world's leading orange producer, with an output almost as high as that of the next three countries combined (the United States, India, and China). Orange groves are located mainly in the state of São Paulo, in the southeastern region of Brazil. Oranges, whose flavour may vary from sweet to sour, are commonly peeled and eaten fresh or squeezed for juice ora"

regmatches(str1,gregexpr("\\borange\\b",tolower(str1),perl=TRUE))[[1]]
#[1] "orange" "Orange"


 length(regmatches(str1,gregexpr("\\borange\\b",tolower(str1),perl=TRUE))[[1]])
#[1] 2
A.K.

Subject: [R] str_count counts the substring

I am trying to count the number of times a word occurs in a string.
and using str_count function from the package stringr. This function counts
the substrings as well.
Is there a way in which I can exclude the substring count and just take the
exact match.
Thanks in advance.
