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=ma
trix(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
