Multivariate Transformations
It depends on what you are after. I am by no means a wunderkind when it comes to transformation, but in the package vegan type ?wisconsin and that should give you a start, but if you know what transformations you would like to preform then apply should do what you need with whatever transformation you are trying to use.

Hello folks, many multivariate anayses (e.g., structural equation modeling) require multivariate normal distributions. Real data, however, most often significantly depart from the multinormal distribution. Some researchers (e.g., Yuan et al., 2000) have proposed a multivariate transformation of the variables. Can you tell me, if and how such a transformation can be handeled in R? Thanks in advance. With best regards Holger --------------- Yuan, K.-H., Chan, W., & Bentler, P. M. (2000).
