clauswilke / colorblindr Goto Github PK

Hi Claus,

I'm trying to install the colorblindr package with the following command on my windows computer with R version 3.4.2: devtools::install_github("clauswilke/colorblindr")

It looks like the installation is failing because it's not working correctly with colorspace. The error I get is:

preparing package for lazy loading
Error : object 'deutan' is not exported by 'namespace:colorspace'
ERROR: lazy loading failed for package 'colorblindr'
removing 'C:/Users/ClaraShaw/Documents/R/win-library/3.4/colorblindr'
Installation failed: Command failed (1)

I installed cowplot and colorspace today, so I'm not sure what's wrong, and I couldn't find much on troubleshooting this issue.

Thanks so much for your help!

the package colorspace is not getting installed... Returning some error

Hi! Great 📦 !

I think setting last_plot() as the default value for plot in view_cvd(), cvd_grid() and edit_colors() could make life easier for interactive use.

Hi. I previously had colorblindr working on my R studio setup, but not longer. So I reinstalled. This is what I'm getting.

I downloaded a fresh cowplot and colorspace.
I have R 3.5 on Mac OS and R Studio Version 1.1.463
on MacOS 13.3

Hi Claus,
When I try running cvd_grid(), I get the following error: "Error in desaturate(c, severity) : unused argument (severity)"

In the attached screenshot, I did the following:

1. I uninstalled colorspace.
2. I reinstalled colorspace using the code provided in the README (https://github.com/clauswilke/colorblindr/blob/master/README.md).
3. I also ran the installation code for cowplot and colorblindr to show that both are installed and up to date.
4. I then proceeded with the example in the README, which works until I try the cvd_grid function.

Since I was running R v. 3.3.1, I decided to update R to the latest version. I then reinstalled the tidyverse and devtools packages, and then ran the code in the README. However, I still get the same error.

Let me know what further information I can provide to solve this issue. (Still very new at this!)

Thanks,
Irene

Hello,

I just wanted to give a short heads up about a minor issue I stumbled upon:

when playing around with this great package I just realized some unexpected behaviour with when using geom_label() in combination cvd_grid() - somehow the color of this particular geom stays untouched:

library(tidyverse)
library(colorblindr)
#> Loading required package: colorspace

p <- tibble(label = 'test') %>%
  ggplot()+
  geom_segment(aes(x = -1, xend = 1,y = 0, yend = 0, color = label))+
  geom_label(aes(x=0,y=0,label = label, color = label))+
  theme_void()

cvd_grid(p)

^{Created on 2019-08-27 by the reprex package (v0.3.0)}

cheers,
Kosmas

Could the package include a function that calculates some kind of a "colorblindness accessibility score" given a color (or palette)?

The code here http://mkweb.bcgsc.ca/colorblind/code.mhtml#page-container appears to be able to calculate correction (see getcorrection fcn) to provide "variants".

Given such a score, a color that is similar (in hue?) but better wrt colorblindness perception could be found and used to improve a specific set of colors?

Personally I'd like to use such functionality to improve the accessibility for colorblind perception of this specific color palette: https://github.com/KTH-Library/ktheme/blob/master/R/palette.R#L42-L81

Thanks for making this available, I would love (my colleagues) to use the information in http://serialmentor.com/dataviz/ to create better plots AND use colorblind-friendly colors. Is it possible to separate the actual color palettes from the colorblind simulation functionality? That way they can use those palettes without having to (know how to) use devtools to install development packages.

I successfully installed "cowplot" and "colorspace" as instructed, but failed to install 'colorblindr'. Very disappointed since I have bought the wonderful book "Fundamentals of Data Visualization" but am unable to produce same graphs. Error message is as below. Your help is needed. Thank you.

I juist wanted to confirm that this package doesn't support continuous scales? I'm not missing anything?

Love this package! I just had to upgrade to Beagle Scouts and it looks like it isn't yet available for this release. (You probably already knew, but I figured that I should create a GH issue, just in case!)

Hello!

Do you think it would be possible to create individual functions for each of the colorblind types? I think that it is very useful to display them in a single grid, but it would also be nice to have some flexibility in how we present them.

Happy to help with a PR for this, and also with any help you might like in submitting this to CRAN - this is a super useful package!

Hi,
when I install the "colorbindr" package, I got the error: Does not appear to be an R package (no DESCRIPTION)

Let's say you have an image of three species of flower with an outline of each filled using the OkabeIto color scale. This way, when you view the colorblinr images you also see how colorblindness affects the accompanying visuals that use the same color scheme? Do you have a vignette for how to adding images to these plots before you export them to colorblindr?

We should prepare a proper release. What is still needed? Here are some things I can think about:

• Move github repo to wilkelab. This allows us to add a pkgdown website and host it under wilkelab.org, as in https://wilkelab.org/isoband/ or https://wilkelab.org/ungeviz/.
• Check dependencies. Do we depend on the development version of cowplot, as the readme states? The listed dependency is >0.8.0, and the version on CRAN is 0.9.4, so this should be fine.
• No packages other than base R should be listed under "Depends". All other dependencies should be listed under "Imports".
• Update installation instructions in the readme.
• Review all vignettes.
• Remove the ggplot2 color scales vignette. It is outdated and there are other packages now that focus specifically on color scales, e.g. paletteer.

Something else?

Install via downloading zip and running devtools::install("") seems to have worked.

one currently needs to scroll down to see what it is about, just noticed that when sharing the link.
