Filter a voteList object

Usage

# S3 method for class 'voteList'
filter(.data, ..., .table = "metaList", drop.levels = TRUE)

Arguments

.data: A voteList object.
...: Logical expressions passed to [dplyr::filter()], evaluated against the sub-table specified by .table. Multiple conditions are combined with &.
.table: Name of the sub-table to filter on. One of "metaList" (default), "voteList", "votePerParty", "sponsorList", or "categoryList". The matching ids are then used to subset all other sub-tables.
drop.levels: If TRUE (default), unused factor levels are dropped from all sub-tables after filtering.

Value

A voteList object containing only the votes whose rows in .table match the filter conditions.
