VCorpus: Volatile Corpora

Description

Create volatile corpora.

Usage

VCorpus(x, readerControl = list(reader = reader(x), language = "en"))
as.VCorpus(x)

Arguments

x

For VCorpus a Source object, and for as.VCorpus an R object.

readerControl

a named list of control parameters for reading in content from x.

reader

a function capable of reading in and processing the format delivered by x.

language

a character giving the language (preferably as IETF language tags, see language in package NLP). The default language is assumed to be English ("en").

Value

An object inheriting from VCorpus and Corpus.

Details

A volatile corpus is fully kept in memory and thus all changes only affect the corresponding R object.

PCorpus provides an implementation with permanent storage semantics.

# NOT RUN {
reut21578 <- system.file("texts", "crude", package = "tm")

# }
