Bundled subcorpora — subcorpus_bundle-class • polmineR

A subcorpus_bundle object combines a set of subcorpus objects in a list in the the slot objects. The class inherits from the partition_bundle and the bundle class. Typically, a subcorpus_bundle is generated by applying the split-method on a corpus or subcorpus.

# S4 method for subcorpus_bundle
show(object)

# S4 method for subcorpus_bundle
merge(x, name = "", verbose = FALSE)

# S4 method for subcorpus
merge(x, y, ...)

# S4 method for subcorpus
split(
  x,
  s_attribute,
  values = NULL,
  prefix = "",
  mc = getOption("polmineR.mc"),
  verbose = TRUE,
  progress = FALSE,
  type = get_type(x)
)

# S4 method for corpus
split(
  x,
  s_attribute,
  values = NULL,
  prefix = "",
  mc = getOption("polmineR.mc"),
  verbose = TRUE,
  progress = FALSE,
  type = get_type(x),
  xml = "flat"
)

# S4 method for subcorpus_bundle
split(
  x,
  s_attribute,
  prefix = "",
  progress = TRUE,
  mc = getOption("polmineR.mc")
)

Arguments

object	An object of class `subcorpus_bundle`.
x	A `corpus`, `subcorpus`, or `subcorpus_bundle` object.
name	The name of the new `subcorpus` object.
verbose	Logical, whether to provide progress information.
y	A `subcorpus` to be merged with `x`.
...	Further `subcorpus` objects to be merged with `x` and `y`.
s_attribute	The s-attribute to vary.
values	Values the s-attribute provided shall assume.
prefix	A character vector that will be attached as a prefix to partition names.
mc	Logical, whether to use multicore parallelization.
progress	Logical, whether to show progress bar.
type	The type of `partition` to generate.
xml	A `logical` value.

Details

Applying the split-method to a subcorpus_bundle-object will iterate through the subcorpus, and apply split on each subcorpus object in the bundle, splitting it up by the s-attribute provided by the argument s_attribute. The return value is a subcorpus_bundle, the names of which will be the names of the incoming partition_bundle concatenated with the s-attribute values used for splitting. The argument prefix can be used to achieve a more descriptive name.
