Count Words in a String

Description

Count the number of words that appear within a character string.

Usage

StrCountW(x)

Arguments

x	a vector of strings to be parsed.

Details

This is just a wrapper for a fine regexpr. It uses the expression \b\W+\b to separate the words. The code \W is equivalent to [^[:alnum:]_]) wheras [:alnum:] contains [:alpha:] and [:digit:]. So everything that is not an alphanumeric character, a digit or a _ (underscore) is used as separator for the words to be counted.

Value

an integer defining the number of word in the string
