Code should be placed in three backticks as shown below

features <- binGenome( genomeTxDb )
  64 genes were dropped because they have exons located on both strands of the same
  reference sequence or on more than one reference sequence, so cannot be represented
  by a single genomic range.
  Use 'single.strand.genes.only=FALSE' to get all the genes in a GRangesList object,
  or use suppressMessages() to suppress this message.
Error in .Call2("Rle_constructor", values, lengths, PACKAGE = "S4Vectors") :
