I am using Gviz to plot several tracks. I create a
GenomeAxisTrack() and then several
AnnotationTrack()s that I feed to
plotTracks(). This produces a stacked output of tracks with annotated arrows as I want but the displays are linear. In some cases have the complete genomes and I know they are circular (like some bacterial/viral chromosomes), how can I display the plots as circular?
I tried feeding to
GRanges() object with a
Seqinfo() object specifying the
isCircular=TRUE flag, but this didn't change the resulting plot.
Here is minimal code to create a linear plot, I would like a circular one where the first and last arrow join up:
library(Gviz) library(stringr) track <- AnnotationTrack(start=c(1,5,7), end=c(2,6,10), strand=c('+','+','-'), stacking="dense", fill=c('red','blue', 'black')) pdf(file=paste("test","pdf", sep=".")) plotTracks(track) dev.off()
