ucie

The goal of ucie is to map data into CIELab Color Space.

Installation

You can install the released version of ucie from CRAN with:

install.packages("ucie")
or
devtools::install_github("mikelkou/ucie")

Usage

library(ucie)

# returns a data frame with names of data points and colors (hex colors or Lab coordinates)
data2cielab(dataset, WL, Wa, Wb, S, LAB_coordinates)

Example

This is a basic example which shows you how to solve a common problem:

library(ucie)
## basic example code
df <- data.frame(V1=runif(100,  0,1), V2=runif(100,  0,5), V3=runif(100,  0,30))
data_with_colors <- data2cielab(df, Wb=1.2, S=1.6)

UCIE maps to narrow LAB spectrum microbiome data

U-CIE is a great tool, so simple idea and robust implementation!

I am trying to apply U-CIE to my soil microbiome data (amplicon - 16s rRNA), especially the sample sites. After the UMAP of the community matrix (SITES X GENERA) I supplied the 3d UMAP data to the tool (attached file).

My problem is that the projection of U-CIE to colors is narrow, mostly around green.
I tried to toggle the parameters (both in UI and in R package) but I fail to expand the color coverage.

Is there a way, to cover a bigger part of the color space?
