Get Attribute Size (of Positional/Structural Attribute).
Use cl_attribute_size to get the total number of values of a
positional attribute (param attribute_type = "p"), or structural
attribute (param attribute_type = "s"). Note that indices are
zero-based, i.e. the maximum position of a positional / structural
attribute is attribute size minus 1 (see examples).
cl_attribute_size(corpus, attribute, attribute_type,
registry = Sys.getenv("CORPUS_REGISTRY"))corpus |
name of a CWB corpus (upper case) |
attribute |
name of a p- or s-attribute |
attribute_type |
either "p" or "s", for structural/positional attribute |
registry |
path to the registry directory, defaults to the value of the environment variable CORPUS_REGISTRY |
registry <- if (!check_pkg_registry_files()) use_tmp_registry() else get_pkg_registry()
Sys.setenv(CORPUS_REGISTRY = registry)
