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
