R Documentation

Count the number of sentences

Description

Return the count of sentences in a corpus or character object.

Usage

nsentence(x)

Arguments

`x`	a character or corpus whose sentences will be counted

Value

count(s) of the total sentences per text

Note

nsentence() is now deprecated for all usages except tokens objects that have already been tokenised with tokens(x, what = "sentence"). Using it on character or corpus objects will now generate a warning.

nsentence() relies on the boundaries definitions in the stringi package (see stri_opts_brkiter). It does not count sentences correctly if the text has been transformed to lower case, and for this reason nsentence() will issue a warning if it detects all lower-cased text.

Examples

# simple example
txt <- c(text1 = "This is a sentence: second part of first sentence.",
         text2 = "A word. Repeated repeated.",
         text3 = "Mr. Jones has a PhD from the LSE.  Second sentence.")
tokens(txt, what = "sentence") |>
    nsentence()
