Arguments

txt

An object of class kRp.txt.trans-class, kRp.tagged-class, kRp.txt.freq-class or kRp.analysis-class.

scheme

One of the following character strings:

• "minor" Start each word with a lowercase letter.

• "all.minor" Forces all letters into lowercase.

• "major" Start each word with a uppercase letter.

• "all.major" Forces all letters into uppercase.

By default an object of class kRp.txt.trans-class is returned. If paste=TRUE, returns an atomic character vector (via kRp.text.paste).
