[R] problem with data for metaMDS analysis please help

[stephen sefick]

am at my wit's end.  I am not sure what is wrong with this data matrix.  It
is sparse because it is a matrix of species, but I have looked at the row
totals and column totals and they are positive.
rmetaMDS(x.d)
Error in if (autotransform && xam > 50) { :
missing value where TRUE/FALSE needed
What is wrong?  And in the future how in God's name do I easily diagnose
whatever problem there is with this data.  I am in debt to anyone who
figures this one out.
Thanks

Stephen
