Currently available options are:
verboselogical; if TRUE then use this as the default
for all functions with a verbose argument
threadsinteger; specifies the number of threads to use in
parallelized functions; defaults to RcppParallel::defaultNumThreads();
the number of threads can be changed only once in a session
print_dfm_max_ndocinteger; specifies the number of documents to display when using the defaults for printing a dfm
print_dfm_max_nfeatinteger; specifies the number of features to display when using the defaults for printing a dfm
base_docnamecharacter; 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_featnamecharacter; stem name for features that are unnamed when they are added, for whatever reason, to a dfm through an operation that adds features
base_compnamecharacter; stem name for components that are created by matrix factorization
language_stemmercharacter; language option for char_wordstem(),
tokens_wordstem(), and dfm_wordstem()
pattern_hashtag, pattern_username
character; regex patterns for (social media) hashtags and usernames respectively, used to avoid segmenting these in the default internal "word" tokenizer
tokens_block_sizeinteger; specifies the number of documents to be tokenized at a time in blocked tokenization. When the number is large, tokenization becomes faster but also memory-intensive.
tokens_localecharacter; specify locale in stringi boundary detection in
tokenization and corpus reshaping. See stringi::stri_opts_brkiter().
When called using a key = value pair (where key can be
a label or quoted character name)), the option is set and TRUE is

When called with no arguments, a named list of the package options is returned.
When called with reset = TRUE as an argument, all arguments are
options are reset to their default values, and TRUE is returned
invisibly.
