Hi,
I wonder whether R can finish the following project:
I want to make a chart to represent 10 genes. Each gene has orientation and
length. Therefore, a gene can be represented by arrows.
Can R be used to draw 10 arrows in one line ?

Yes, but you need to be a bit more specific... When it comes to graphs
and drawing lines, there isn't much R can't do...
