I need to make a graphic to show problems on different parts of chromosomes (think of a graphic showing the number of frayed threads as colors along different parts of a worn out rope). I want to draw bars going from left to right across a page and color different parts of the bars in different shades. Each graphic will need to have several bars of different lenghts corresponding to the different lenghts of the chromsomes. Is there a package around that can help me draw custom bars of different colors? I am a hardcore SAS guy who is just learning R so I am mostly clueless.
How can I draw bars

arrows and I don't remember what package, but I will see if I can remember.

Hi Raymond, The gradient.rect and color.scale functions (in plotrix) may not do exactly what you want, but the code within them is almost certainly relevant to your problem. Jim
