In pvsR: An R package to interact with the Project Vote Smart API for scientific research

Description

This function is a wrapper for the Rating.getSigList() method of the PVS API Rating class which dumps special interest groups (SIGs) according to category and state. The function sends a request with this method to the PVS API for all category and state IDs given as a function input, extracts the XML values from the returned XML file(s) and returns them arranged in one data frame.

Usage

Rating.getSigList(stateId="NA", categoryId)

Arguments

stateId	(optional) a character string or list of character strings with the state ID(s) (default: "NA", for national) (see references for details)
categoryId	a character string or list of character strings with the category ID(s) (see references for details)

Value

A data frame with a row for each special interest group and columns with the following variables describing the special interest group:
sigs.sig*.sigId,
sigs.sig*.parentId,
sigs.sig*.name.
