does anyone else have a problem using demo(targets) to have a look at the example in the rtracklayer package?
The error is given after chunk 6
> view <- browserView(session, range, + hide = c("refGene", "mgcFullMrna", "intronEst"), + dense = "knownGene", squish = "cons44way") Error in normGenomeRange(range, object) : 'range' should be a genome string, RangesList, GRanges or Seqinfo
range is an IRanges object an produced apparently by
range <- ranges(targetTrack[top,]) * -10
The session is clean without any other packages loaded.
Thanks for any help and advice.
