`hcl.colors()` contains HCL approximations of all sequential and diverging palettes from `rcartocolors`. Analogously for `viridis` and `RColorBrewer`. See:

Thanks for all this work, very much appreciated! A couple of comments regarding suitability of the palettes - also in combination with potential color vision deficiencies: * For qualitative palettes...

* I'm not a fan of picking colors from your favorite painters or directors. For visualizing categorical or numeric data other considerations are (also) important than just having colors that...

My feeling is that it is the implicit categorization that makes spotting the odd one out easier. I would have like to see a comparison with: * Using, say, seven...

All the functions that I am aware of also use `col2rgb()` and `rgb()` under the hood. Both are `.Call`s to `C_col2rgb` and `C_rgb` internally. So I would have expected them...

Good point. When you have millions of colors then indexing them would probably be a good idea. You could also have a look at the underlying C code to see...

Thanks for having a go at this Josh @joshuaulrich ! Comments: * _`index2char()` names:_ Unfortunately, for this application, `index2char()` internally relies on `as.character()` rather than `format()`. My guess is that...

I have supported `start = NA` and `end = NA` in `window.zoo` and `window

Thanks, Duncan! Just a small addition: The `citation()` functionality will also be extended soon in R-devel to recognize packages installed via `remotes::install_github()` and adapt the "note" and "url" fields correspondingly...

Thanks for putting this together, I think this is very useful! However, this should be in the task view, not in the README. The README is just in the GitHub...
