bootstrap_dfm: Bootstrap a dfm

Description

Create an array of resampled dfms.

Usage

bootstrap_dfm(x, n = 10, ..., verbose = quanteda_options("verbose"))

Arguments

x

a character or corpus object

n

number of resamples

...

additional arguments passed to dfm

verbose

if TRUE print status messages

Value

A named list of dfm objects, where the first, dfm_0, is the dfm from the original texts, and subsequent elements are the sentence-resampled dfms.

Details

Function produces multiple, resampled dfm objects, based on resampling sentences (with replacement) from each document, recombining these into new "documents" and computing a dfm for each. Resampling of sentences is done strictly within document, so that every resampled document will contain at least some of its original tokens.

Examples

# NOT RUN {
# bootstrapping from the original text
txt <- c(textone = "This is a sentence.  Another sentence.  Yet another.", 
         texttwo = "Premiere phrase.  Deuxieme phrase.")
bootstrap_dfm(txt, n = 3)
         
# }
