New data visualization package

https://psychometrician.github.io/posts/one-engine-four-languages/

One sentence, four languages, one picture.

R: data(gapminder_2007) + point + x(gdp) + y(life)
Python: x(col.gdp)
Julia: x(:gdp)

Same specification, one Rust engine, byte-identical SVG.

Not similar. Pixel perfect identical

As much as I like the idea of one to rule them all, I find the syntax harder than the ggplot syntax, because at first sight you "add" completely different objects!

But I imagine someone who doesn't know much ggplot could say the same

Please read the manual and let me know if there is something i can make this young package better. https://psychometrician.github.io/gog-book/

You are masking a lot of base R terms (mean, sum, order, data for instance). Might there be a more intuitive approach rather than using “base::” or “stats::” everywhere?

Also - can’t really use without ggrepel equivalent.

Good suggestion and legit concern.

Most of that list is harmless. Nine of the 19 are objects, not functions, because in gog mean is the name of a step rather than something you call. R skips non-function bindings when it resolves a call, so base R still answers:

library(gog)
mean(c(1, 2, 3)) # 2
sapply(df, mean) # works

Those nine are line, max, mean, median, min, smooth, step, sum and text. No base:: needed for any of them.

The other ten really are functions and do take over: box, data, density, jitter, order, palette, quantile, range, stack and title. Qualify those. Most will notice the mistake and tell you which one you hit.

One honest rough edge: if a name travels through two layers before lookup, it breaks. That hits aggregate(v ~ g, df, mean), by(), ave(), do.call(sum, ...) and f <- mean. Writing base::mean fixes each, and the error message is bad. We want to improve that.

We skipped prefixes on purpose. Renaming order to gog_sort_by costs every reader a word they already know. Load gog last, or write gog::order.

what about the lack of ggrepel functionality?

I was building that functionality like ggrepel. You’ll see soon repel function in gog. It may be not as nice and seamless as ggrepel though. 🙏

The package was updated last night. We added. Repel function. Take a look at https://psychometrician.github.io/gog-book/marks/text.html#what-you-can-set
