Re: [R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Gavin Simpson]

If you want to stick with or at least compare a mulivariate tree with
other approaches (like CCA or mvabund or boral) then the partykit
package provides an implementation of a multivariate tree model, using
conditional inference trees (i.e. you use conditional inference to
decide if spits are "significant" and stop splitting when they aren't
rather than the classic build a big tree and prune it back with
cost-complexity pruning and cross-validation.

An illustration with the classic hunting spider data set (which was
used in the mvpart paper too IIRC) can be found at the end of one of
the vignettes supplied with partykit:
https://cran.r-project.org/web/packages/partykit/vignettes/ctree.pdf

When I used this recently to replicate an analysis from a book chapter
I wrote a few years back, the partykit implementation worked well
after a little fiddling, but some of the plot options for the terminal
nodes don't work so well if your species response matrix has many
columns in it (i.e. lots of species).

Re: [R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Gavin Simpson]

Right, but mvabund fits quite different types of model to that fitted
in a multivariate tree, which can be seen as an unsupervised
constrained clustering of the multivariate species response matrix.

All the best

Thank you very much Ralf.

I am looking for alternatives to the classic CCA community analysis, and I
was thinking into machine learning techniques.

Re: [R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Ralf Schäfer]

Indeed! To expand on this: if you need a tutorial for mvabund, we once analysed 
some categorical multivariate data and provided a tutorial:
http://dx.doi.org/10.1007/s10646-015-1421-0
Paper and tutorial are freely available on researchgate

There are also many other methods, but to point you to some, it would be good 
if you were more specific than „community- environment relationships“.

Ralf

Re: [R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Torsten Hauffe]

As far as I remember, on Windows you will need to download and install the
Rtools first (https://cran.r-project.org/bin/windows/Rtools/) because some
parts of mvpart need to be compiled.

You can analyse multiple species-environment relationships with the mvabund
package. This is not fancy machine-learning but solid likelihood statistic.

HTH,
Torsten

Re: [R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Ralf Schäfer]

Manuel,

I just checked, it is currently still compatible. So you can download from the 
archive and install from source - at least on Linux and OS X, nut sure about 
Windows.

However, there are certainly other packages that can partition multivariate 
ecological data, though I am not aware of other packages for use with 
multivariate regression trees.

Re: [R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Manuel Spínola]

Thank you Ralf,

But I guess is not going to be newer versions and could be incompatible
with newer version of R, so at some moment there will be no accessibility
to the package.

Dear Manuel

despite it has been removed, it should still work.
At least I used it last year - just install the version from the archive 
manually:
https://cran.r-project.org/src/contrib/Archive/mvpart/

Best regards
Ralf

[R-sig-eco] mvpart alternatives and machine learning multivariate analysis

[Manuel Spínola]

Dear list members,

As mvpart has been removed form the CRAN repository, Is there any r package
that do similar analysis (multivariate partitioning)?

Also, is there any other machine learning technique to do multivariate
analysis as done in ecology to asses multiple species-environment
relationships?

Thank you very much in advance,

Manuel
