We wanna do a graph to show the Syntenic links between a linkage map and physical map visualized using Circos

source("http://bioconductor.org/biocLite.R")

biocLite("OmicCircos")

Each line will represents a connection between the position of a particular marker in our linkage map (black; scale in cM) and a homologous sequence in physical map (various colors; scale in Mb). The idea is to do something like this picture:



I have a strutured family (parental, F1 and F2) that was sequenced and aligned agains the reference genome. I did a linkage map using r/onemap (CRAN) to check the recombination fraction of the markers in the F2 family (only markers with Mendelian Inheritance). Now I have the groups obtained by the recombination in this format:

> maps
[[7]]

Printing map:

6 markers            log-likelihood: -49.90696 

MS33_8248325 represents the marker where we have the chromossome (M33) and position (8248325 in the chr) informations and the cM postion in the second collum.

How should I show the comparizon between linkage map and physical map to prove that they are in agreement??
looks like that "OmicCircos" is a good idea, but I cannot find a tutorial to generate a graph like this one presented here where is divided into two sides (right: chromossomes and left: linkage groups).

I was working in a script trying to edit this command line that it was provided by OmicCircos totorial:

library (OmicCircos)

options (stringsAsFactors=FALSE) ;
set.seed(1234) ;

ind.num <-20
seg.po<- c(20:50)
link.num <- 10

sim.out<- sim.circos (seg=seg.num, po=seg.po, ind=ind.num, link=link.num, link.pg=link.pg.num)

seg.f<-sim.out$seg.frame
seg.v<-sim.out$seg.mapping
link.v<-sim.out$seg.link
link.pg.v<-sim.out$seg.link.pg
