Hi Ansley
It looks good to me but I did not run the analysis as I am too lazy to install
"indicspecies". The inclusion of the raw data is a great help.

Subject: Re: [R] Indicator Species analysis; trouble with multipatt
Thanks for the replies.
I have fixed the problem. I only need to reorganized my data. Now my question
is about asking questions correctly. I hope I've got it. Please find the
script attached here.
R Version 3.2.2
I am looking for indicator species with Indicspecies package. After running
the function multipatt, I get the following error:
Error in is.factor(x) : object 'groups1' not found
**Is this reproducibility satisfactory? I fixed the problem by reorganizing my
csv file. I was trying to be efficient when making my groups and that was
causing the trouble.
Thanks.

Hi Ansely,
As Jim points out we really need some sample data to go with the code.
Have a look at ?dput which is the best way to supply sample data here or have
a look at

asking questions here---including discussions of using dput()
