Filter the strata_name-strata_level pair in a summarised_result

Usage

filterStrata(result, ...)

Arguments

result: A summarised_result object.
...: Expressions that return a logical value (strataColumns() are used to evaluate the expression), and are defined in terms of the variables in .data. If multiple expressions are included, they are combined with the & operator. Only rows for which all conditions evaluate to TRUE are kept.

Value

A summarised_result object with only the rows that fulfill the required specified strata.

library(omopgenerics)
