similar to: Drawing a colour wheel - bug in hcl?

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

Dear R-help, Could any of you direct me to a function for plotting a grid of colours, directly specified by a matrix of hex colour codes? In other words I'm looking for a heatmap() or image()-like function to which I can specify the colour of each grid location directly, rather than providing a numerical matrix and a 1D-colour scale (heatmap, image, levelplots,NeatMap...). I'm surprised

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

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

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 ?

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

Hi all, I'm trying to generate barplots from simple but long (~100000-row) data files, in which each bar will comprise two stacked 'sub-bars'. All the upper sub-bars will have the same hue, and all the lower bars will, likewise, have another uniform hue. However, I wish to specify the luminance (aka brightness) of each bar (i.e., each whole bar comprising two sub-bars) separately,

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

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 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:

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

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
