as_sbo_dictionary: Coerce to dictionary

In sbo: Text Prediction via Stupid Back-Off N-Gram Models

Description

Coerce objects to sbo_dictionary class.

Usage

as_sbo_dictionary(x, ...)

## S3 method for class 'character'
as_sbo_dictionary(x, .preprocess = identity, EOS = "", ...)

Arguments

x	object to be coerced.
...	further arguments passed to or from other methods.
.preprocess	a function for corpus preprocessing.
EOS	a length one character vector listing all (single character) end-of-sentence tokens.

Details

This function is an S3 generic for coercing existing objects to sbo_dictionary class objects. Currently, only a method for character vectors is implemented, and this will be described below.

Character vector input: Calling as_sbo_dictionary(x) simply decorates the character vector x with the class sbo_dictionary attribute, and with customizable .preprocess and EOS attributes.

Value

A sbo_dictionary object.
