How can I plot positions on chromosomes using R. I put a little example to better explain. So I've a dataframe for each sample containing positions of interest :
Chr Pos 1 100 1 300 2 30 10 1000 11 2000
And I want to plot that on chromosomes like that (Here there are 6 samples A,B,C,D,E and F). each point represent the position in the dataframe
Anyone can help me ?
