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

# S3 method for corpus

  ...
)

# S4 method for dfm
print(

  ...
)

# S4 method for fcm
print(
  x,

# S3 method for kwic
print(
  x,
  max_nrow = quanteda_options("print_kwic_max_nrow"),
  show_summary = quanteda_options("print_kwic_summary"),
  ...
)

# 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"),
  ...
)

Arguments

x: the object to be printed
max_ndoc: max number of documents to print; default is from the print_*_max_ndoc setting of quanteda_options()
max_nchar: max number of tokens to print; default is from the print_corpus_max_nchar setting of quanteda_options()
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()
max_nkey: max number of keys to print; default is from the print_dictionary_max_max_nkey setting of quanteda_options()
max_nval: max number of values to print; default is from the print_dictionary_max_nval setting of quanteda_options()
max_nrow: max number of documents to print; default is from the print_kwic_max_nrow setting of quanteda_options()
max_ntoken: max number of tokens to print; default is from the print_tokens_max_ntoken setting of quanteda_options()
