Convert a krpoltext data.table to a quanteda corpus

Creates a quanteda::corpus() object from a data.table loaded by load_campaign_booklet() or load_party_statements(). The text column is used as the document text; all other columns become document-level variables (docvars).

Usage

as_quanteda_corpus(x, text_field = "text", docid_field = NULL, ...)

Arguments

x

A data.table (or data.frame) with at least a text column.

text_field

Character; name of the column containing document text. Defaults to "text".

docid_field

Character or NULL; name of the column to use as document IDs. If NULL, row numbers are used.

...

Additional arguments passed to quanteda::corpus().

Value

A quanteda corpus object.

Examples

if (FALSE) { # \dontrun{
ps <- load_party_statements()
corp <- as_quanteda_corpus(ps)

# Use a subset
ps_2020 <- get_docs("party_statements", year = 2020)
corp_2020 <- as_quanteda_corpus(ps_2020, docid_field = "id")
} # }
