Remove a corpus from the list of loaded corpora of the corpus library (CL).
cl_delete_corpus(corpus, registry = Sys.getenv("CORPUS_REGISTRY"))name of a CWB corpus (upper case)
path to the registry directory, defaults to the value of the environment variable CORPUS_REGISTRY
An integer value 1 is returned invisibly if a previously loaded
corpus has been deleted, or 0 if the corpus has not been loaded and has not
been deleted.
The corpus library (CL) internally maintains a list of corpora including
information on positional and structural attributes so that the registry file
needs not be parsed again and again. However, when an attribute has been
added to the corpus, it will not yet be visible, because it is not part of
the data that has been loaded. The cl_delete_corpus function exposes a
CL function named identically, to force reloading the corpus (after it has
been deleted), which will include parsing an updated registry file.
