The goal of linkET is to visualize simply and directly a matrix
heatmap based on ‘ggplot2’. Note: all functions of network have been
merged in netET package.
You can install the released version of linkET from
GitHub with:
# install.packages("devtools")
devtools::install_github("Hy4m/linkET", force = TRUE)
packageVersion("linkET")This is a basic example which shows you how to solve a common problem:
