corpus_subset: Extract a subset of a corpus

Usage

corpus_subset(x, subset, ...)

Arguments

x	corpus object to be subsetted
subset	logical expression indicating the documents to keep: missing values are taken as false
...	not used

Value

corpus object, with a subset of documents (and docvars) selected according to arguments

Examples

summary(corpus_subset(data_corpus_inaugural, Year > 1980))
summary(corpus_subset(data_corpus_inaugural, Year > 1930 & President == "Roosevelt"))
