corpora.compare.list: The corpora.compare function for a list of dtm's

In kasperwelbers/corpus-tools: tools for corpus analysis

Description

The corpora.compare function for a list of dtm's

Usage

corpora.compare.list(x, subcorpus = NULL, method = "each_to_all",
  return.df = F, window.size = 3, .progress = "text", ...)

Arguments

x	either a named list of document term matrices, or a single dtm (in which cast the subcorpus argument must be given)
subcorpus	if x is a single dtm, subcorpus should be a vector of the length and order of the dtm rows. Each value of subcorpus then represents a separate corpus.
method	different ways to compare corpora. "each_to_all" compares each corpus to a corpos consisting of all other corpora. "window" compares each corpus to a corpus consisting of the previous and/or next corpora (see window.size). The order will be determined by sorting the dtm names (or the subcorpus values) with the order function.
return.df	logical. If True, the results are returned as a data.frame. Otherwise as a list.
window.size	A vector of integers. If method is 'window', this determines which previous and next corpora are used to compare a corpus to. For example: if 3, then each corpus will be compared to a corpus consisting of the 3 previous and 3 next corpora. A corpus itself will not be used to create the comparison corpus. Note that the first and last [window.size] corpora cannot be compared to a full window.
...	additional arguments to be passed to the corpora.compare function

Value

a list or data.frame with the corpora.compare results for each dtm.
