[R] Enquiring examples to get the results of two tests

[Sophy]

Please help me to provide examples to run the following two tests.

1. multivariate shapiro test
2.  multivariate Levene's test to test if the variance of each population is homogeneous for correlated multiple populations.

Especially what packages and commands can be used for these two test. Thanks for your support and great help.
