extra control for breaks? - as in image() about colourvalues

[mdsumner]

Actually, having zlim as well would be awesome, so that we can easily control the absolute scale without specifying breaks - I'll have a closer look at how this might fit in colourvalues

I see now that it's a colourvalues-like function, but maybe only the addition of the breaks argument and control to colour_values()?

In the absence of directly supporting a breaks argument, you can supply the "cuts" directly

colourvalues::colour_values( cut(1:20, breaks = 3) )
 [1] "#440154FF" "#440154FF" "#440154FF" "#440154FF" "#440154FF" "#440154FF" "#440154FF" "#21908CFF" "#21908CFF"
[10] "#21908CFF" "#21908CFF" "#21908CFF" "#21908CFF" "#FDE725FF" "#FDE725FF" "#FDE725FF" "#FDE725FF" "#FDE725FF"
[19] "#FDE725FF" "#FDE725FF"

colourvalues::colour_values_rgb( cut(1:20, breaks = 3) )
      [,1] [,2] [,3] [,4]
 [1,]   68    1   84  255
 [2,]   68    1   84  255
 [3,]   68    1   84  255
 [4,]   68    1   84  255
 [5,]   68    1   84  255
 [6,]   68    1   84  255
 [7,]   68    1   84  255
 [8,]   33  144  140  255
 [9,]   33  144  140  255
[10,]   33  144  140  255
[11,]   33  144  140  255
[12,]   33  144  140  255
[13,]   33  144  140  255
[14,]  253  231   37  255
[15,]  253  231   37  255
[16,]  253  231   37  255
[17,]  253  231   37  255
[18,]  253  231   37  255
[19,]  253  231   37  255
[20,]  253  231   37  255

Is this along the lines of what you're after?

Gee didn't think of that, colour the factor index - need to explore 👍

@mdsumner I haven't looked at this issue since my last comment; is this still relevant for you?

[mdsumner]

oh no, I built it into palr which is a better fit I think, can just close
