Dear Bioconductor mailing list. I am using the aCGH package (http://www.bioconductor.org/packages/rele ase/bioc/vignettes/aCGH/inst/doc/aCGH.pdf, http://www.bioconductor.org /packages/release/bioc/manuals/aCGH/man/aCGH.pdf) to analyse some arrayCGH data. I am trying to generate plots within the package, from my aCGH.obj (called all.acgh in my case) such as the following: #summary plot plot(all.acgh) #basic log2 ration plot across the genome, one sample plotGenome(all.acgh, samples=2, naut = 22, Y = TRUE, X= TRUE, data = log2.ratios(all.acgh), yScale = c(-2, 2), samplenames = sample.names(all.acgh), ylb = "Log2Ratio") These generate plots with data points plotted correctly, but with the x-axis labels all bunched up on the left hand side of the plot and unreadable. These labels are supposed to delineate the different chromosomes across the genome (1-24) with each datapoint representing a log2 ratio. The example data provided with the package works perfectly. I have formatted by data in the exact same way. I also have no problem with the other functions I am running on my aCGH.obj. There are no warning messages produced. Any help in fixing these labels would be much appreciated.
