The first example of the vignette doesn't work reproducibly.

[JiaxiangBU]

Here is the vignette file link.

In the first example, when I run this code,

opt.sd <- optimize.portfolio(R, SD.portf, 
                             optimize_method="ROI", 
                             momentFUN="sigma.robust")
opt.sd

R told me Error: paste0("package:", plugin) %in% search() || requireNamespace(plugin, .... is not TRUE but does't show which packages I have to install or update.

Here is my sessionInfo().
