---|
an integer (count) of the number of documents or features
ndoc
returns the number of documents in an object
whose texts are organized as "documents" (a corpus,
dfm, or tokens object, a readtext object from the
readtext package).
nfeat
returns the number of features from a dfm; it is an
alias for ntype
when applied to dfm objects. This function is only
defined for dfm objects because only these have "features". (To count
tokens, see ntoken
.)
nfeature
is the deprecated form of nfeat
.
