Error in rowSums(x) : 'x' must be an array of at least two dimensions (Vegan:oecosimu)

问题

I am trying to use the application oecosimu in Vegan package.

library(sna)
 library(permute)
library(lattice)
library(vegan)
library(bipartite)
bio<-read.csv("/home/vicar66/Raw_data/Jan12/98percents_April_16/otu_table/Chapter1/no_bloom_bio_data_L3.txt")
rownames(bio)<-bio[,1]
bio[,1]<-NULL
bio_m<-as.matrix(bio)
a<-oecosimu(bio_m,bipartite::C.score,"swap")

but I keep having this error message: Attaching package: 'bipartite'

The following object is masked from 'package:vegan':

nullmodel

Error in rowSums(x) : 'x' must be an array of at least two dimensions Calls: oecosimu -> nullmodel -> rowSums Execution halted

**first column first row is empty. First row are rownames

Anyone have encountered this problem yet?

Thanks!
