Bundle Class

Description

A bundle is used to combine several objects (partition, context, features, cooccurrences objects) into one S4 class object. Typically, a class inheriting from the bundle superclass will be used. When working with a context_bundle, a features_bundle, a cooccurrences_bundle, or a context_bundle, a similar set of standard methods is available to perform transformations.

Usage

## S4 replacement method for signature 'bundle'
name(x) <- value

## S4 method for signature 'bundle'
length(x)

## S4 method for signature 'bundle'
names(x)

## S4 replacement method for signature 'bundle,vector'
names(x) <- value

## S4 method for signature 'bundle'
unique(x)

## S4 method for signature 'bundle,bundle'
e1 + e2

## S4 method for signature 'bundle,textstat'
e1 + e2

## S4 method for signature 'bundle'
x[[i]]

## S4 replacement method for signature 'bundle'
x[[i]] <- value

## S4 method for signature 'bundle'
x$name

## S4 replacement method for signature 'bundle'
x$name <- value

## S4 method for signature 'bundle'
sample(x, size)

## S4 method for signature 'list'
as.bundle(object, ...)

## S4 method for signature 'textstat'
as.bundle(object)

## S3 method for class 'bundle'
as.data.table(x, keep.rownames, col, ...)

## S4 method for signature 'bundle'
as.matrix(x, col)

## S4 method for signature 'bundle'
subset(x, ...)

## S4 method for signature 'bundle'
as.list(x)

## S3 method for class 'bundle'
as.list(x, ...)

## S4 method for signature 'bundle'
get_corpus(x)

Arguments

`x`	a bundle object
`value`	character string with a name to be assigned
`e1`	object 1
`e2`	object 2
`i`	An `integer` value to index a bundle object.
`name`	The name of an object in the `bundle` object.
`size`	number of items to choose to generate a sample
`object`	A `bundle` object.
`...`	Further parameters
`keep.rownames`	Required argument to safeguard consistency with S3 method definition in the `data.table` package. Unused in this context.
`col`	columns of the `data.table` to use to generate an object.

Slots

corpus: The CWB corpus the objects in the bundle are based on, a length 1 character vector.
objects: An object of class list.
p_attribute: Object of class character.
encoding: The encoding of the corpus.

Examples

parties <- s_attributes("GERMAPARLMINI", "party")
parties <- parties[-which(parties == "NA")]
party_bundle <- partition_bundle("GERMAPARLMINI", s_attribute = "party")
length(party_bundle)
names(party_bundle)
get_corpus(party_bundle)
party_bundle <- enrich(party_bundle, p_attribute = "word")
summary(party_bundle)
parties_big <- party_bundle[[c("CDU_CSU", "SPD")]]
summary(parties_big)
p <- partition("GERMAPARLMINI", date = "2009-11-11")
pb <- partition_bundle(p, s_attribute = "party")
names(pb)
pb[["NA"]] <- NULL
names(pb)
pb <- partition_bundle("GERMAPARLMINI", s_attribute = "party")
pb$SPD # access partition names "SPD" in partition_bundle pb
pb <- partition_bundle("GERMAPARLMINI", s_attribute = "party")
pb$"NA" <- NULL # quotation needed if name is "NA"
use("polmineR")
pb <- partition_bundle("REUTERS", s_attribute = "id")
coocs <- cooccurrences(pb, query = "oil", cqp = FALSE)
dt <- as.data.table(coocs, col = "ll")
m <- as.matrix(dt[, 2:ncol(dt)], rownames = dt[["token"]])
