I'm trying to overlay coverage plots of individual chromosomes from different experiments to get a quick overview of probable CNVs. I've tried using simple xy plot, ggplot and plotrix packages of R (and I'm a real novice in R) but it seems that my linux machine with 64GB of memory is unable to handle the task. I've also reduced my file size by putting only the coordinates and the coverages derived from samtools pileup into a single file.
Can someone comment on this and suggest a better and more memory efficient way of doing this? Thank you.
