Hi all,

I'm currently using the package GenomeGraphs for the vizualization of
different types of biological data.
Additionally to this data, I want to vizualize ChIP-Chip scores in this
figure.

For this purpose, I generated an object of class "GenericArray".  The
attribute "intensity" contains
the scores, the attribute "probeStart" contains the start and "probeEnd" the
end of the enrichment score.

However, I encounter a problem in the vizualization of this object when
using the  "probeEnd" attribute.

For example the following  snippet works:

gdPlot(makeGenericArray(probeStart=c(1,5),intensity=matrix(c(1,2),ncol=1)),minBase=0,maxBase=10)

but using "probeEnd" leads to an error...
gdPlot(makeGenericArray(probeStart=c(1,5),probeEnd=c(2,7),intensity=matrix(c(1,2),ncol=1)),minBase=0,maxBase=10)


Maybe, someone has an idea to circumvent this problem. Or maybe a better
idea of vizualizing scores using GenomeGraphs.


Cheers,
          Philippe
