The example DEXSeqDataSet code gives and error in version 1.17.4 and 1.16.3.

Thanks

Alex

  countData <- matrix( rpois(10000, 100), nrow=1000 )
  sampleData <- data.frame(
      condition=rep( c("untreated", "treated"), each=5 ) )
  design <- formula( ~ sample + exon + condition:exon )
  groupID <- rep(
      paste0("gene", 1:10),
      each= 100 )
  featureID <- rep(
      paste0("exon", 1:10),
      times= 100 )
  DEXSeqDataSet( countData, sampleData, design,
              featureID, groupID )

Error:
