Most universities use specific color combinations to express their unique brand identity. The unicol package provides the colors and color palettes of various universities for easy plotting and printing in R. We collect and provide a diverse range of color palettes for creating scientific visualizations.
Our primary goal is to make it simple to create beautiful visualizations that are in accordance with institutional regulations and style guides. Assuming that you have some R code for creating an image, unicol allows you to directly use the color palette of your institution.
The latest release of unicol is available from CRAN at https://CRAN.R-project.org/package=unicol:
install.packages('unicol') # install from CRAN client
library('unicol') # load the packageThe current development version can be installed from its GitHub repository at https://github.com/hneth/unicol/:
# install.packages('devtools') # install pkg
devtools::install_github('hneth/unicol')The unicol package is based on the R package unikn and requires it for key functionality.
The unicol package provides colors and color palettes, whereas the unikn package provides color-related functions:
library(unicol) # for color palettes
library(unikn) # for color functionsThe unicol package currently provides 273 color palettes from 116 institutions.
(See the vignette All color palettes for an overview of included color palettes and institutions.)
Figure 1 illustrates 50 random color palettes (with 215 colors):
Figure 1: A sample of 50 unicol palettes (containing 215 colors).
As the unicol palettes are provided as vectors of R colors, they can
simply be used as the col argument of R graphics functions. For
instance, we can use the MIT colors (of the Massachusetts Institute of
Technology) in a bar plot (with the barplot()
function of the base R graphics package) as follows:
barplot(height = 1:10,
col = mit,
main = "Using the MIT colors")
To modify a color palette (e.g., by resizing the palette or adding
transparency), we use the usecol() function of the
unikn package:
barplot(height = 1/sqrt(1:16),
col = usecol(mit, n = 16),
main = "A color gradient of MIT colors")
Here are some some additional examples how the color palettes from unicol can be used:
# Viewing a color palette:
unikn::seecol(yale, main = "The primary colors of Yale University")
# Demo plots:
unikn::demopal(berkeley_1, type = 2, main = "The colors of Berkeley, University of California", seed = 3)
unikn::demopal(limerick_1, type = 3, main = "Using the colors of the University of Limerick", seed = 3)
The current range of color palettes included in unicol is highly selective and incomplete. However, we are happy to include color palettes and institutions from all over the world.
If you are missing a color palette, you can easily create and add it.
For instructions on how this can be done, please see the documentation
of the newpal() function (of the
unikn package). The
vignette on Institutional
colors
provides a corresponding example.
Call for contributions: Collecting color palettes
- Are you using the unikn functions to create your own color palettes?
If you do, please let us know (e.g., on this GitHub issue) so that we can include it in future versions of the unicol package. To enable us to verify and provide credit to your contributions, please send us the following information:
- your code (e.g., the
newpal()command creating your color palette), - your reference or source information (e.g., the names of the institution and some URL with color definitions),
- your name and some valid contact information (e.g., an Email address).
We’re looking forward to your inputs and contributions (at this GitHub issue)!
