I'm looking for an R package and coding to simulate a multivariate Garch process with jump diffusion. Is there a package or R code I can replicate and modify?

After a quick search I found this paper: High-dimensional GARCH process segmentation with an application to Value-at-Risk by Haeran Cho and Karolos K. Korkas. Link to their paper here.
In their abstract they reference their package, segMGarch
, which is available on CRAN (Documentation can be found here).
I found this with very little effort. Consider looking into CRAN packages, other questions on StackOverflow (I found this one in the related posts), or simply Googling it.
