subsetFilter-class.RdThis class represents the action of applying a filter on the subset of data resulting from another filter. This is itself a filter that can be incorporated in to further set operations. This is similar to an intersectFilter, with behavior only differing if the component filters are data-driven.
subsetFilters are constructed using the equivalent binary set operators
"%&%" or "%subset%". The operator is not symmetric, as the
filter on the right-hand side will take the subset of the filter on the
left-hand side as input. Left-hand side operands can be a filter or list of
filters, while the right-hand side operand must be a single
filter.
filtersObject of class "list", containing the component filters.
filterIdObject of class "character"
referencing the filter applied.
Class "filter", directly.
