p_attributes

Get p-attributes.

Description

In a CWB corpus, every token has positional attributes. While s-attributes cover a range of tokens, every single token in the token stream of a corpus will have a set of positional attributes (such as part-of-speech, or lemma). The available p-attributes are returned by the p_attributes-method.

Usage

p_attributes(.Object, ...)

## S4 method for signature 'character'
p_attributes(.Object, p_attribute = NULL)

## S4 method for signature 'corpus'
p_attributes(.Object, p_attribute = NULL)

## S4 method for signature 'slice'
p_attributes(.Object, p_attribute = NULL, decode = TRUE)

## S4 method for signature 'partition_bundle'
p_attributes(.Object, p_attribute = NULL, decode = TRUE)

Arguments

`.Object`	A length-one `character` vector, or a `partition` object.
`...`	Arguments passed to `get_token_stream`.
`p_attribute`	A p-attribute to decode, provided by a length-one `character` vector.
`decode`	A length-one `logical` value. Whether to return decoded p-attributes or unique token ids.

Details

The p_attributes-method returns the p-attributes defined for the corpus the partition is derived from, if argument p_attribute is NULL (the default). If p_attribute is defined, the unique values for the p-attribute are returned.
