In RcppCWB: 'Rcpp' Bindings for the 'Corpus Workbench' ('CWB')

Get Vector with Counts for Positional Attribute.

Description

The return value is an integer vector. The length of the vector is the number of unique tokens in the corpus / the number of unique ids. The order of the counts corresponds to the number of ids.

Usage

get_count_vector(corpus, p_attribute, registry = Sys.getenv("CORPUS_REGISTRY"))

Arguments

corpus	a CWB corpus
p_attribute	a positional attribute
registry	registry directory

Value

an integer vector

Examples

y <- get_count_vector(
  corpus = "REUTERS", p_attribute = "word",
  registry = get_tmp_registry()
  )
df <- data.frame(token_id = 0:(length(y) - 1), count = y)
df[["token"]] <- cl_id2str(
  "REUTERS", p_attribute = "word",
  id = df[["token_id"]], registry = get_tmp_registry()
  )
df <- df[,c("token", "token_id", "count")] # reorder columns
df <- df[order(df[["count"]], decreasing = TRUE),]
head(df)
