I try to draw features like genes, transposable elemets, GC content along chromosomes
are there any R packages available?
Did you look on Bioconductor packages - http://www.bioconductor.org/
If you're not tied to R, I would highly recommend AnnotationSketch (part of GenomeTools). They have a web service, but you can download and compile the code on your local system. It's a C library, but they have bindings for Python, Ruby, and Lua as well.
Have a look at genoplotR. It might be able to do what you want from R. It is highly tunable.
Just a random example below;
This is awesome! I have been looking for a tool like this. Thanks!
