Print methods for quanteda core objects

Print method for quanteda objects. In each max_n* option, 0 shows none, and -1 shows all.

# S3 method for corpus
print(
  x,
  max_ndoc = quanteda_options("print_corpus_max_ndoc"),
  max_nchar = quanteda_options("print_corpus_max_nchar"),
  show_summary = quanteda_options("print_corpus_summary"),
  ...
)

# S4 method for dfm
print(
  x,
  max_ndoc = quanteda_options("print_dfm_max_ndoc"),
  max_nfeat = quanteda_options("print_dfm_max_nfeat"),
  show_summary = quanteda_options("print_dfm_summary"),
  ...
)

# S4 method for dfm
show(object)

# S4 method for dictionary2
print(
  x,
  max_nkey = quanteda_options("print_dictionary_max_nkey"),
  max_nval = quanteda_options("print_dictionary_max_nval"),
  show_summary = quanteda_options("print_dictionary_summary"),
  ...
)

# S4 method for dictionary2
show(object)

# S4 method for fcm
print(
  x,
  max_nfeat = quanteda_options("print_dfm_max_nfeat"),
  show_summary = TRUE,
  ...
)

# S4 method for fcm
show(object)

# S3 method for tokens
print(
  x,
  max_ndoc = quanteda_options("print_tokens_max_ndoc"),
  max_ntoken = quanteda_options("print_tokens_max_ntoken"),
  show_summary = quanteda_options("print_tokens_summary"),
  ...
)

show_summary	print a brief summary indicating the number of documents and other characteristics of the object, such as docvars or sparsity.
...	not used
max_nfeat	max number of features to print; default is from the print_dfm_max_nfeat setting of quanteda_options()
