Hi everyone, I'm using the package "GenomeGraphs" for the visualization of my ChIPChip data. The vizualization works fine until I try to vizualize the "probeEnd" of a Probe in a graph. For easier understanding of my problem I created the following minimal example, where only the positiveExample is working. library(GenomeGraphs) positiveExample <- makeGenericArray(probeStart=seq(1,5), intensity=matrix(c(1,2,3,5,4), ncol=1)) negativeExample <- makeGenericArray(probeStart=seq(1,5), intensity=matrix(c(1,2,3,5,4), ncol=1), probeEnd=seq(2,6) ) gdPlot(list(positiveExample,negativeExample), minBase = 0, maxBase = 7) Any help would be appreciated.
