nProteins-methods: Returns the number of identified proteins.

In RpepXML: R interface to the pepXML standard

Description

These methods return the number of proteins that have been identified for any individual seach hit. The class of the returned object will depend on the argument provided, as described below. Note that simplification is attemplted by 'sapply'.

Methods

signature(object = "SearchHit")

an object of class "SearchHit" is used as parameter and a single integer value is returned.

signature(object = "SearchResult")

an object of class "SearchResult" is used as parameter and an integer is returned of length equal to the number of search hits in the search result. If the search result has no search hits, 0 is returned.

signature(object = "SpectrumQuery")

an object of class "SpectrumQuery" is used as parameter the output will depend on the structure of the data. A spectrum without search results will return 0. If one search result exists, the returned value will be an integer or a matrix, depending on the number of search hits. If the sectrum query contains several search results, a list is returned.

signature(object = "MSMSpepXML")

an object of class "MSMSpepXML" is used as parameter and a list of matrices or integers of length equal the number of spectrum queries is returned.
