Dear PGLMM gurus, Unfortunately, currently there is no `predict(object, newdata = ...)` method for `communityPGLMM` class, and it is only possible to extract the fitted values with `fitted.communityPGLMM`. In particular,...

Should we switch from [plyr](https://github.com/hadley/plyr) to [purrr](https://github.com/tidyverse/purrr)? Check also [multidplyr](https://github.com/hadley/multidplyr) (a backend for dplyr) to parallelize the code. + see [the comprehensive tutorial on this topic by Jenny Bryan](https://jennybc.github.io/purrr-tutorial/bk01_base-functions.html) and...

question

Need to implement efficient rarefaction function based on [RTK](https://github.com/hildebra/Rarefaction).

enhancement

It should be quite easy to parallelize plyr-dependent functions to speed up processing of data. Functions that could be modified to accept parallel option: - [x] `phyloseq_mult_raref` - [ ]...

enhancement

Currently, no tests other than examples in the manual are part of the package. See [testthat](https://github.com/hadley/testthat) package (+[test workflow example](http://r-pkgs.had.co.nz/tests.html)).
