About half our team can wrangle and plot as fast as we can think of ideas. It creates an incredibly tight cycle time between us having ideas and getting answers; sometimes many (e.g. 10-20+) of those cycles in a single meeting. Before we used R, it would require someone jotting down things to investigate and reporting back in the next meeting. But we can do ~80% of whatever people can think of on the spot (more involved research questions can take more time).

The unique qualities of R that allow this are that it's so easy to use, extremely reliable for package installation (problems occur approximately never), and the tidyverse makes it incredible easy to translate ideas into code, not only in its broad, easy to understand and powerful vocabulary, but in there being little 'nesting' required; instead working left to right and top to bottom (via the magrittr pipe) - i.e. your code, for the most part, is like reading a page in a book.
