gradienttext is an R package that works with the ggtext package to create gradient text labels on ggplot graphs.
You can install the development version of gradienttext from GitHub with:
# install.packages("devtools")
devtools::install_github("samiaab1990/gradienttext")
Note: ggtext and ggplot2 must be already installed for the make_gradient() function in the package to work.
