[R] data type problem for vegan package

[keunhchoi at gmail.com]

Dear all,

I'm using R2.8 version,  and am trying to do NMDS and calculate other
diversity indices in vegan package.
The problem is that it works with a small set of data (43 X 23; row by
column), but the following error message comes up with a larger data set (43
X 104) (it seems not large to me at all). I made it sure that all data are
of numeric type as required.

>gh1.H=diversity(gh1)
>FUN(newX[, i], ...) : invalid 'type' (character) of argument

If someone has an idea, please...
