tokens_sample: Randomly sample documents from a tokens object

In koheiw/quanteda.core: Quantitative Analysis of Textual Data

Description

Sample tokenized documents randomly from a tokens object, with or without replacement. Works just as sample() works, for document-level units (and their associated document-level variables).

Usage

tokens_sample(x, size = ndoc(x), replace = FALSE, prob = NULL)

Arguments

x	the tokens object whose documents will be sampled
size	a positive number, the number of documents or features to select
replace	logical; should sampling be with replacement?
prob	a vector of probability weights for obtaining the elements of the vector being sampled.

Value

A tokens object with number of documents or features equal to size, drawn from the tokens x.
