dplyr_methods {fr}

dplyr methods for fr_tdr objects

Description

Some basic dplyr functions are re-implemented here for for fr_tdr objects. The input is converted with as.data.frame() before being passed to the dplyr function. The resulting tibble object is converted back into a fr_tdr object, matching table- and field-specific metadata where possible by using as_fr_tdr() and specifying the .template argument.
