DFSource: Create a DFSource object from a data frame

Description

This function will create a DFSource object from a data frame that contains at least columns id and text, but may contain several more. VCorpus will use this to read in each row from the data frame into a PlainTextDocument, storing additional variables in its metadata. It will then combine all those PlainTextDocuments in a VCorpus object.

Usage

DFSource(x)

Value

A DFSource object containing the encoding set to "", the number of rows (length), the current position (position=0), the type of reader to use (reader=readDF), and the content (x).

Arguments

x

A dataframe with at a minimum a text and id column, and a row for each document to be stored in a corpus.

Examples

(df=data.frame(id=1:3,text=c("First text","Second text","Third text"),
               title=c("N1","N2","N3")))
DFSource(df)
