Is it possible to plot SHAP values for a single observation in R like you can in python?
This post make a nice plot for single observations:

The force_plot in python seems to vary quite a bit from the R version. Can I recreate such a plot with the SHAPforxgboost library, or does anyone have ideas on what I can do with ggplot2?

shap.initjs()
shap.force_plot(explainer.expected_value[1], shap_values[1], data_for_prediction)

Here is the plot from Python.

Hi @nicolaivinther,
You can run Python code inside R using the reticulate package and shuffle data between the two. Saves you from reinventing the wheel!

install.packages("reticulate")
library(reticulate)
help(reticulate)
