Description

Count results of search hits, or of a given feature in tokens

Usage

count_tcorpus(

  meta_cols = NULL,
  hits = NULL,
  feature = NULL,
  count = c("documents", "tokens", "hits"),
  wide = T
)

Value

A data table

Arguments

tc

A tCorpus

meta_cols

The columns in the meta data by which the results should be grouped

hits

featureHits or contextHits (output of search_features, search_dictionary or search_contexts)

feature

Instead of hits, a specific feature column can be selected.

count

count_tcorpus(tc, hits=hits, meta_cols='president')
count_tcorpus(tc, hits=hits, meta_cols='president', wide=FALSE)
