similar to: New grDevices::hcl.colors()

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-palettes-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

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

Hi, The move to sRGB is nice, is there any interest in adding an interface to lcms, http://www.littlecms.com, to allow gamut matching? I can think of a lot of instances where I would like to render a figure as it would appear on my printer. This is probably best done as a separate package though, at least at first.

Hi. I want to use image() with colours that are indexed by two variables. Indexing by one variable is easy: library(colorspace) x <- seq(from=0, to=1,len=30) z <- outer(x,1i*x,"+") image(Re(z),col=hcl(seq(from=0,to=100,len=15),c=100)) OK, so far so good. Now, I want the colour to be a more complicated function of z, in which both the hue and luminance change (thus the colours

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

Dear r-devel, I have implemented a function to create color palettes with improved contrast and logical order, compared with the built-in ones: source("arni.colors.R") # code is given below barplot(rep(1,100), col=arni.colors(100), space=0, border=0, axes=F) par(mfrow=c(2,1)) # rainbow() has too much green... barplot(rep(1,50), col=rev(rainbow(50,end=0.7)), space=0, border=0,

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

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

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

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 Mr. Leppe, See the attached excel file that covers the current Tripp Lite HID compatible UPS systems. There is also an attached Word document covering the UPSC / UPSCMD / UPSRW information from the specific UPS systems. Let me know if this is adequate to get our additional HID compatible products added to the NUT HCL listing. Tripp Lite Eric K. Cobb Product Management Specialist 1111

We have tested your latest NUT distributions against our HID USB compatible UPS systems and would like to know what is needed and/or who is needed to contact in order to updated the listing of compatible Tripp Lite UPS systems in your HCL list? Hi Eric, From end users of NUT,

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

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?

Hi everyone, I am trying to install colorspace (needed as part of my favourite ggplot2) on R v 2.7.0 running under ubuntu 7.04. The package is provided as source files and the compilation fails as below. I suspect this might be a problem with gcc v3/v4 incompatibility (or anything else), but I don't really know how to resolve it. Any advice will be appreciated - or perhaps somebody has got
