Hi David:
Quick Q: why do some palettes have a hyphen in the name and others not?
I followed the naming conventions of the respective packages that provide
the original for the the HCL-based approximations. But when you specify
the palette name in hcl.colors() all hyphens, spaces, and the
capitalization is ignored anyway:
R> hcl.colors(4, "Dark 3")
[1] "#E16A86" "#909800" "#00AD9A" "#9183E6"
R> hcl.colors(4, "dark3")
[1] "#E16A86" "#909800" "#00AD9A" "#9183E6"
R> hcl.colors(4, "Dark-3")
[1] "#E16A86" "#909800" "#00AD9A" "#9183E6"
R> hcl.colors(4, "Dark----------------3")
[1] "#E16A86" "#909800" "#00AD9A" "#9183E6"
So hopefully this does not lead to too much confusion.
Best wishes,
Z

Hi everyone,
I wanted to draw your attention to a new post on the
developer.R-project.org blog:
https://developer.R-project.org/Blog/public/2019/04/01/hcl-based-color-pale
ttes-in-grdevices/
A new function grDevices::hcl.colors() greatly extends the color
palette
functionality available in base R. Also, the defaults in the
heatmap
functions image() and filled.contour() have been adapted
accordingly.
Feedback is welcome, especially regarding potential problems
with the
changed defaults.
Best wishes,
Z
