There's a delicious time in book writing when I switch from actual writing & making graphs to POLISHING-- smoothing language, adding X-references, and improving graphs that don't pass the smell test.

I'm there now with my book, Visualizing Multivariate Data and Models with R.
What a sweet feeling!

I remember John Fox as one of the most kind R Foundation #rstats members (ca. 2006-2023) giving wise and kind words often. The 1-1 interview he held with several of us, resulting in a useR!2008 pres and the article journal.r-project.org/articles/RJ-... It is sad to miss him. May he rest in peace!

📅Nov 25, 1731 Leonhard Euler first used the symbol _e_ to denote the base of natural logs 2.71728... in a letter to Christian Goldbach.
(Published it first in a 1728 paper.)

Why e? See: bit.ly/4pBYweE
Why was $\rm e$ named $\rm e$? What is the history and rationale behind it?
Why does the constant that Euler discovered have the symbol $\rm e$ and not other symbols? What is the history and rationale behind it?

#rstats Using Rhub: Every time I do `devtools::release()` for a package, it asks if I've checked with Rhub. I always lie, because it was painful and confusing.

Now, I'm prompted to look at `?rhub::rhubv2` but the doc is more like a vignette, and doesn't really tell me how to get started simply.
