R/getAllDistricts.R

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

##' Get basic data on all districts
##' 
##' This function is essentially a wrapper around District.getByOfficeState().
##' @usage getAllDistricts()
##' @return A data frame with a row for each district and columns with the following variables describing the district:\cr districtList.district*.districtId,\cr districtList.district*.name,\cr districtList.district*.officeId,\cr districtList.district*.stateId.
##' @references http://api.votesmart.org/docs/District.html\cr
##' See http://api.votesmart.org/docs/semi-static.html for a list of office IDs or use Office.getOfficesByType(), Office.getOfficesByLevel(), Office.getOfficesByTypeLevel() or Office.getOfficesByBranchLevel().\cr
##' Use State.getStateIDs() to get a list of state IDs.

##' # First, make sure your personal PVS API key is saved as character string in the pvs.key variable:
##' \dontrun{pvs.key <- "yourkey"}
##' # get a list of all districts
##' \dontrun{districts <- getAllDistricts()}
##' \dontrun{head(districts)}
