Get or set global options affecting functions across quanteda.
quanteda_options(..., reset = FALSE, initialize = FALSE)
... | options to be set, as key-value pair, same as
|
---|---|
reset | logical; if |
initialize | logical; if |
When called using a key = value
pair (where key
can be
a label or quoted character name)), the option is set and TRUE
is
returned invisibly.
When called with no arguments, a named list of the package options is returned.

as an argument, all arguments are
options are reset to their default values, and TRUE
is returned
invisibly.
Currently available options are:
verbose
logical; if TRUE
then use this as the default
for all functions with a verbose
argument
threads
integer; specifies the number of threads to use in parallelized functions
print_dfm_max_ndoc
integer; specifies the number of documents to display when using the defaults for printing a dfm
print_dfm_max_nfeat
integer; specifies the number of features to display when using the defaults for printing a dfm
base_docname
character; stem name for documents that are unnamed when a corpus, tokens, or dfm are created or when a dfm is converted from another object
base_featname
character; stem name for features that are unnamed when they are added, for whatever reason, to a dfm through an operation that adds features
base_compname
character; stem name for components that are created by matrix factorization
language_stemmer
character; language option for char_wordstem, tokens_wordstem, and dfm_wordstem
