print: Print a CWB object

In PolMine/rcqp.mac: Interface to the Corpus Query Protocol

Description

Print a CWB object in an exhaustive way. A cqp_flist object is printed just as an integer vector; a corpus is printed as a dataframe where rows represent tokens and columns represent attributes (positional as well as structural); a subcorpus is printed as a cqp_kwic list (or concordance); a cqp_kwic object is printed... as expected.

Usage

 ## S3 method for class 'cqp_flist'
print(x, ...)

 ## S3 method for class 'cqp_corpus'
print(x, from = 0, to = 20, use_value = TRUE, ...)

 ## S3 method for class 'cqp_subcorpus'
print(x, positional.attribute = "word", from = 0, to = 10, ...)

 ## S3 method for class 'cqp_kwic'
print(x, from = 0, to = min(20, nrow(x)-1), 
        print_tokens = function(x, cpos) cqi_cpos2str(
		paste(attr(x, "parent.cqp_corpus.name"),"word", sep = "."), cpos), 
		left.separator = " <<", right.separator = ">> ", ...)

 ## S3 method for class 'cqp_attr'
print(x, ...)

Arguments

x	An rcqp object, created with cqp_flist, corpus, subcorpus, cqp_kwic, or $.cqp_corpus.
from	Select first tokens (for a corpus object) or matches (for a subcorpus or cqp_kwic object) to be printed. As for all CWB data, this index is 0-based.
to	Select last tokens (for a corpus object) or matches (for a subcorpus or cqp_kwic object) to be printed. As for all CWB data, this index is 0-based.
use_value	use value or id for a structural attribute with values.
positional.attribute	Print each token of the subcorpus using the given positional attribute.
print_tokens	A function allowing a fine access to the way tokens are displayed in a concordance.
left.separator	String inserted at the left of the keyword in a concordance.
right.separator	String inserted at the right of the keyword in a concordance.
...	Ignored.

Details

The print command applied on a subcorpus object is a shortcut for :

k <- cqp_kwic(subcorpus)
print(k)

Creating a cqp_kwic object gives more control on the printing options.
