This kind of question is far more suitable for the r-sig-ecology email
list than for ECOLOG. For one thing, the authors of vegan regularly
answer questions there.

Also, to be able to answer your question we need to know more about what
your data look like - str(yourdata) - being a good start, and what
commands you're using.

Hello all,
I have a quick question regarding data format when using the vegan package
in program R for rarefaction. I have played around a bit with the sample
data links and can get these to run fine, but I am having a problem
getting my own data to load properly. When I try to run the rarefaction
command, I get this message, "Error in as.matrix(x) : object 'x' not
found." Not sure if this error is due to the way I am setting up my data
or the pathway to my dataset. Could someone weigh in and let me know what
I am doing incorrectly? Any input on data format would be great. Thanks
in advance for any help.
Bill
