[Bioc-devel] BiomartGeneRegionTrack question

Dear Bioconductor helpers,
I am trying to plot a region of interest using the Gviz package.
I met error when running the following example code:

library(Gviz)
library(GenomicRanges)
bmTrack <- BiomartGeneRegionTrack(start=26682683, end=26711643,

+ chromosome=7, genome="mm9")
