Help: Install package "rugarch"

[Hama]

When I installed package "rugharch", the rstudio showed that "package ‘rugarch’ successfully unpacked and MD5 sums checked". I saw in some forum that i shoul install the missing dependency install.packages("DistributionUtils") to resolve this problem. But, unfortunately, it's the same i can't install "rugarch" package. Someone knows how to solve this problem? Thanks.

@Hama

the rstudio showed that "package ‘rugarch’ successfully unpacked and MD5 sums checked".

If RStudio says the package is successfully installed, then, Can you clarify what your installation problem is? Aren't you able to load the package? If so, please post the corresponding error message.

When i I library the package "rugarch", the rstudio showed: "Le chargement a nécessité le package : parallel
Error: package or namespace load failed for ‘rugarch’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
aucun package nommé ‘expm’ n'est trouvé"

@Hama

aucun package nommé ‘expm’ n'est trouvé"

You are missing a package dependency, you have to install it first.

install.packages("expm")

Also, next time please post the error messages in English. People trying to help you are not always going to be willing to translate them for you.

I successfully downloaded the rugarch package, thank you.
Please did you have any idea how we can solve this problem: "Error in if (model[i] > 0) { : missing value where TRUE/FALSE needed"
