Arguments

txt

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

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.
