I have a large data.frame rows=sites, column=species.  Being a species
matrix it is very sparse and I have found that there are no site rows that
are = 0 and no species = 0 and I am getting and error that reads

x = read.table("shit.txt", sep="\t",header=T, row.names=1)
x.m <- as.matrix(x)
x.t <- t(x.m)
x.d <- as.data.frame(x.t)
metaMDS(x.d)
Error in if (autotransform && xam > 50) { :
  missing value where TRUE/FALSE needed

I would gladly include data, but it is to large for the list >150k.  Any
help would be greatly appreciated.
Thanks
