library(GenomeGraphs) test <- new("MappedRead", start = 1:10, end = 4:13, strand = rep(c("+", "-"), each = 5)) gdPlot(test, minBase = 1, maxBase = 13) There is no analogue to makeBaseTrack for example. You'll notice that the reads are colored according to strand. All that needs to be done is essentially to have start1, start2, end1, end2 and then draw small rectangle, line, small rectangle, for each read.

It would however be more or less trivial to extend to paired end reads.
