Hi Z I think supporting HCL color spaces more, is a *very* good idea. However, I doubt many R users, understand the motivation for HCL color spaces. I've reproduced Ross Ihaka's notes on color, on my personal website: https://sites.google.com/site/spurdlea/exts/ihaka_r_stats_787_10_color.pdf (This has been reproduced with permission). Another good article is:

Hi, I would have expected that I get always 3 colors as result which is not true: hcl.colors(3, alpha=c(0, 0.5, 1)) # 3 colors rainbow(3, alpha=c(0, 0.5, 1)) # 3 colors heat.colors(3, alpha=c(0, 0.5, 1)) # 3 colors terrain.colors(3, alpha=c(0, 0.5, 1)) # 6 colors cm.colors(3, alpha=c(0, 0.5, 1)) # 6 colors topo.colors(3, alpha=c(0, 0.5, 1)) # 9 colors R-Version and

Duncan, thanks for your feedback. I just received your response after sending out mine. You came to the same conclusion. Should I prepare a patch and send it to you so that you can also have a look?

I'm working with the following code below to generate a how do I set the h,c, and l values such that the significant, positive residuals appear different on a grayscale printer from significant grayscale residuals. The challenge as I see it is that one can only distinguish the positive and negative residuals with the hue/. Varying the chroma and the luminance only affect the

Hi All, I'm trying trying to draw a colour wheel (a slice of hcl space) in R. Running the code below doesn't give me what I expect - there's some oddly bright colours of the wrong hue around c(0, 0) and I see three coloured circles (a small magenta, a medium sized yellow and a large cyan). Am I doing something wrong or is there a bug in the hcl code? (Also any suggestions for

Suppose we start with data("Titanic") mosaic(Titanic, shade = TRUE) How do I combine the dashed box contours of shading_Friendly to indicate negative residuals, with three levels of gray: dark for abs(Pearson Resid) > 4, lighter for 4 > abs(Pearson Resid) > 2, and lightest for bs(Pearson Resid) < 2 ?

It looks like the CyberPower Cyber Power Systems CP685AVR supported by usbhid-ups has a favorable device dump linked to the Devices Dumps Library page here: http://networkupstools.org/ddl/Cyber_Power_Systems/CP685AVR.html However, it is not listed anywhere on the Hardware Compatibility List (HCL) page here: http://networkupstools.org/stable-hcl.html This appears to be an omission on the HCL

Anyone familiar with Cyberpower's model numbers? I finally got sick of my Tripplite's USB port going south, all the time, so I'm looking to replace it. The HCL has an entry for a Cyberpower model CP1500AVRLCD. Not listed is the CP1500PFCLCD model, a newer, premium version of the unit; but the HCL does have an entry for the CP1000PFCLCD model. Pretty sure that the CP1500PFCLCD

Hello everyone I am struggling with hcl(). It says on the manpage that "240 yields blue". With this: plot(1:50,pch=16,col=hcl(h=240, c=50, l=1:50)) I get mostly blue, but also some red, dots. Note that h=240 throughout. If 240 is blue, how come there's a red dot there? Or is it just my monitor? Can some colour expert help me on this? -- Robin Hankin Uncertainty Analyst

I'm looking for a driver for and old uninterruptible power supply (UPS), Eaton Powerware 9125 2500U. I want to use it with my FreeNAS server. I looked a the list and didn't see a driver for it: http://www.networkupstools.org/stable-hcl.html?manufacturer=Eaton I see a driver for the 9130; any idea whether it will work with a 9125? Any other ideas for connecting the 9125 to a FreeNAS

I''m needing to put a network card on a test server XCP 1.0. I''m seeing the citrix hcl (http://hcl.xensource.com) and I''m a doubt. I base that on which version to look for a compatible card? If the kernel is the same as in 5.6.0 FP1, but if the version of XCP uses the hypervisor 3.4.2 neither appears on the list. ps: I had a RTL-8169 but stopped working with update 0.5

Hi Eric, From end users of NUT,

I've found RColorBrewer useful for its qualitative palettes, but wished that it could generate more than 12 qualitative palettes (e.g. with Set3). Any suggestions for alternative color palette generators that can handle e.g. 18 distinctive colors? (I'm aware of using rainbow(), but this doesn't generate enough distinct colors when the number of palettes is large). Thanks, Andrew

Dear useRs, we have just released a new version (1.2-0) of the "colorspace" package: http://CRAN.R-project.org/package=colorspace In addition to the infrastructure for transforming colors between different color spaces (RGB, HSV, HCL, and various others) and support for different types of color palettes (qualitative, sequential, diverging), there is now a new graphical user
