Lets-plot: An interactive Python plotting library using ggplot's API

Tidyverse is much, much harder to write functions for, which is pretty bad for beginners. The API is lovely, but the non-standard evaluation causes real problems for people.

True story: writing tidyverse functions is so hard that I once worked for a company with business critical code running in incredibly long R-scripts with almost no functions, and 100 line pipes.

While that may be an extreme example, base-R is much, much easier to get started writing functions for (like I've been using R for a decade now, and the "idiomatic" way to use NSE with ggplot and dplyr has changed multiple times over that time).

Meanwhile, base-R is fugly, but its solid and backwards-compatible to a fault.

As a huge fan of tidyverse, I have to agree. Tidy eval is anything but.

However, once they get that right, then tidyverse is close to perfection

I think the newish “interpolation” syntax with double braces {{ }} is getting there.

See, it's changed again!

Damnit Hadley, why must you do this to me?

(Really I'm bitter because I know that I'll end up maintaining a bunch of important code in version N-2 of Hadley's NSE adventures at some point in the future).

Changed, yes, and finally in the right direction I would say!

... and the following is what I mean. I think this is as close to clean and understandable as it can get, for most use cases (variables in functions, including creating new variables):

The biggest difficulty of NSE is not the syntax, but the requirement to hold parallel mental models while writing the code: symbolic expressions and value manipulation. Juggling will always be difficult.
