Hmm. I never got that error but this issue seems to be that you don't have the R package "quadprog". So I might try to fix this by running the command install.packages("quadprog")

I got the same question, even after install.packages("quadprog") and library(quadprog) . Error in e$fun(obj, substitute(ex), parent.frame(), e$data) : worker initialization failed: there is no package called ‘quadprog’ Hope that anybody could answer the question!

We encountered the same issue when running on R 4.4.1. Eventually, we resolved the problem by downgrading R to version 4.2.1. We suspect it might be due to incompatibility between the ‘quadprog’ package and the higher version of R. Hopefully, this solution can help everyone with this issue.
