Hi All, 

I am new to ConsensusClusterPlus. I followed its tutorial in Bioconductor:

d = read.table("data.txt",header=T)

# Choose the top 5000 most variable genes

mads=apply(d,1,mad)
d=d[rev(order(mads))[1:5000],]

# Normalize the data
d = sweep(d,1, apply(d,1,median,na.rm=T))

# Do clustering

results = ConsensusClusterPlus(d,maxK=6,reps=50,pItem=0.8,pFeature=1,
                               clusterAlg="hc",distance="pearson", 
                              writeTable = T, seed=seed,plot="pdf")

I got an error:

Error in ConsensusClusterPlus(d, maxK = maxK, reps = 50, pItem = 0.8,  : 
  d must be a matrix, distance object or ExpressionSet (eset object)

I then checked 

d[1:5,1:5]

It looks like d is a matrix. Am I missing something so the error pops up?

Thanks!

d = as.matrix(read.table("data.txt",header=T)) fixed the problem!
