Dear all, I need to draw a graph of a specific chromosome with each gene marked on it. An examplified gene list is as shown below.
gene chromosome start end
Act-1 I 20 2000
Atp-1 I 3000 4000
Kin-4 I 6000 8000
...........................
i can't figure out how to draw it using R (I am R beginner). It's easy to transform the above data to the following one.
gene chromosome start gene_width
Act-1 I 20 1980
Atp-1 I 3000 1000
Kin-4 I 6000 2000
...........................
I think it is a histogram, but different gene has different width. Could anyone help to solve this problem? I believe this is a very common question for many bioinformatics beginners.
Thanks a lot!
