Description

Some utility methods.

Usage

concat(..., collapse="", rm.space=FALSE)
## S3 method for class 'character':
wordcount(x)
## S3 method for class 'ngram':
wordcount(x)

Arguments

...

Input text(s).

A string or vector of strings.

collapse

A character to separate the input strings if a vector of strings is supplied; otherwisethis does nothing.

rm.space

Details

concat() is a utility for concatenating strings together. This is handy because if you want to generate the n-grams for several different texts, you must first put them into a single string. wordcount() counts words. Currently a "word" is a clustering of characters separated from another clustering of charactersby at least 1 space. That is the law.

Examples

Run this code

library(ngram)

words <- c("a", "b", "c")
wordcount(words)
str <- concat(words)
wordcount(str)
