Think it would be sensible to include in here as it's dfe-specific recommended general R functions. Other packages to consider joining up with as we do it would be:
dfeshiny - I'd expect static plot code lives here in dfeR, and then that can easily be combined with something in dfeshiny for reactivity?
afcolours - where we should be aiming to pull our default colours from (though following the AF colours guidance we can look to add more and use the instructions for testing our own)
ggdfe - a similar package started elsewhere in DfE
Not sure if this needs to be it's own package (dfeplot?), but need some things to help style plots consistently.
