R is a complex program. If you can't work out how to find the documentation, I doubt you will be able to use R.
-- David Kirby (in response to a vague question on where to find documentation for R)

Oh, gosh, this is getting whimsical.
R, I surmise, is a mutable tool that enables the user to do what they want. Knapped flint for the Stone Age statistical fool, plasma arc for the expert and learned savant.
R is a friend to all manner of men. The perfect companion, the servant complete. It gently informeth the clueless and then, reveals the essence unto the esthete.

In general, it's much easier to create output from a R object than create an R object from output.

I'm looking for an effective way to highlight how much the RUB/USD exchange rate has changed over recent years. I think classic line graph doesn't really convey it, so I tried with a barchart adding lines for the percentage change. Suggestions from the fediverse?

You need to get the hang of reading the online help. The information required is actually there in ?dotchart --- it's just tersely and obscurely expressed. A certain degree of optimism is required. You need to ***believe*** that the information is there; then ask yourself "What could they possibly mean by what they have written that would tell me what I need to know?".

If 'fools rush in where angels fear to tread', then Bayesians 'jump' in where frequentists fear to 'step'.

This is one of those cases, in my opinion, where R's documentation drops you into a flat landscape, in the middle of nowhere, in a thick mist.

If we do that, I predict that the total amount of r-help time wasted on it will exceed the CPU time saved by orders of magnitude.

There's probably some examples, but there are some examples of people using
solve(t(X) %*% W %*% X) %*% W %*% Y
to compute regression coefficients, too.

Your example requires all choices of 1541 out of 3000, which I would expect to take somewhere near age-of-the-universe seconds to compute. The code uses a clever nested computation due to Gail et al which will cut that time down to infinity/10.
