Obtains the size of a certain number of predefined corpora. The total size of a corpus is important for calculating term frequencies.

corpus_size(corpus = c("taxon_annotations", "taxa", "gene_annotations",
  "genes"))

Arguments

corpus

the name of the corpus, currently one of "taxon_annotations", "taxa", "gene_annotations", and "genes". (At present "gene_annotations" is pending support by the Phenoscape API.) Unambiguous abbreviations are acceptable.

Value

the size of the specified corpus as an integer number.

Details

Corpus sizes are cached per session after they have first been obtained. Thus, if the Phenoscape KB changes, a session needs to be restarted to have those changes be reflected.

Examples

corpus_size("taxa")
#> [1] 785
corpus_size("taxon_annotations")
#> [1] 809892
