A package to fit multivariate Gaussian mixture model

[yu_chem]

Hello.
I ask you about R package or others
Now I have expression data of some genes from 10x genomics

I want to get multivariate Gaussian mixture model fitted to data for showing relationship between some genes.

I hope you introduce me the package (R package or others) to calculate multivariate Gaussian mixture model.

If possible, a package, which not connect server on internet, is best.

thank you for your answer

sincerely
