expand_investigators: Expand nested investigator fields

In steveneschrich/pgreportr: NIH Program Grant Reporting Library

Expand nested investigator fields

Description

The Investigator field is a nested tibble. This function expands the nested tibble, creating multiple rows for the same grant with different investigators in each row.

Usage

expand_investigators(d, ...)

Arguments

d

Details

The tidyr::unnest function provides the ability to nest a tibble within a tibble field. We use this to embed the investigator tibble into the grants tibble, so that filtering and counting will proceed as normal. This is one way to accomplish a relational set of tables.

However, when we need access to this embedded tibble, we can do two different things.

First, we can use purrr::map to iterate over the embedded tibbles.

Second, we can expand the tibble into many tibbles.

This function accomplishes the second option.
