height

height

...

further parameters

p_attribute

A character vector with p-attribute(s) for counting.

decode

A logical value, whether to turn token ids into decoded strings.

Slots

objects

Object of class list the partitions making up the bundle

corpus

Object of class character the CWB corpus the partition is based on

s_attributes_fixed

Object of class list fixed s-attributes

encoding

Details

The merge-method aggregates several partitions into one partition. The prerequisite for this function to work properly is that there are no overlaps of the different partitions that are to be summarized. Encodings and the root node need to be identical, too.

The enrich() method will fill the slot stat of the partition objects within the bundle with a count for the designated p-attributes. If .Object is a subcorpus_bundle, the output class will be a partition_bundle.

Examples

# merge partition_bundle into one partition
gparl <- corpus("GERMAPARLMINI") %>%
  split(s_attribute = "date") %>% 
  merge()
use(pkg = "RcppCWB", corpus = "REUTERS")

pb <- partition_bundle("REUTERS", s_attribute = "id")
barplot(pb, las = 2)

sc <- corpus("GERMAPARLMINI") %>%
  subset(date == "2009-11-10") %>%
  split(s_attribute = "speaker") %>%
  barplot(las = 2)
