Filter a data.frame by primary-key values (or arbitrary columns)

Convenience helper to subset a data.frame by a set of named values. The filters argument is a named list mapping column names to allowed values (vector). When strict = TRUE, unknown filter columns raise an error.

Usage

st_filter(df, filters = list(), strict = TRUE)

Arguments

df

A data.frame to filter.

filters

Named list of filtering values, e.g. list(country = "PER").

strict

Logical; when TRUE unknown filter columns cause an error.

Value

A subsetted data.frame (same columns as df).
