Hi, 

I ve been trying to use edgeR for RNA-Seq Dierential Expression and I am trying to use in R the plotMDS function but I get the following cryptic error message 

> plotMDS( cds , main = "MDS Plot for Count Data", labels = colnames( cds$counts ))
Error in cmdscale(as.dist(dd), k = ndim) : 
  'k' must be in {1, 2, ..  n - 1}

Would any of you have an idea what this error  mean. 

Thanks for your help

Best regards 

Nicolas
