Now you really have to tell us what do you mean with "true" residuals. From the point of view adonis() "true residuals" are dissimilarities, but it seems that you want something completely different. What that may be? Your concept of "residual" seems to be different from mine, so please explain what you want to have.

If you want to have residuals of raw data, you can use rda() and its residuals() method. However, if you intend to use these in subsequent analysis, please note that labdsv functions at least seem to assume that data are non-negative, but it does not check this.
