[R-sig-eco] Rarefaction related queries

[Rajendra Mohan panda]

Dear All

I am struggling to rarefy my species data. If I use rarefy function in
 vegan, I get two columns for all the dataset (312 rows and 6220 columns)
even if I change the sample value.

If I use rarefaction function of *Jenna Jacobs - email at jennajacobs.org
<email at jennajacobs.org>, *I get different rows and columns for the same
input data.

If I understand properly, the data with sample =5 should yield one-fifth of
the total rows*columns of input data but that does not come.

Kindly advise what are technical errors in rarefaction by Jenna Jacobs
usually we come across,and what should we take care while doing rarefaction
of our data.

Your valuable suggestions are highly appreciated.

With Best Regards
