Christophe Hi Christophe, If you are trying to do what I think you are trying to do, consider drawing the arrow first, with the starting point at the center of the circle, then draw the circle with a fill color the same as the background. This should give you a circle with a nice radial arrow emerging from the edge.

Re: [R] drawing arrows
Duncan mentioned the arrows function, which may do everything you want. But, also look at the my.symbols function in the TeachingDemos package for another way to draw arrows, or to draw your circles and arrows in 1 step. -- Gregory (Greg) L.

[R] drawing arrows with rgl
Hi, I am looking for a package which allows me to draw arrows (cylinders with cones on them, basically) in 3d images produced with rgl. Is such a thing available? I did notice the 'compositions' package, which contains 'arrow3D'. However, it relies on 'tensorA', which fails to install on my machine with the error message copied below. If anyone can help me fix this problem, that would do the trick too.

Is such a thing available? The shapes3d demo in rgl draws cones. You could use the same ideas to draw cylinders. Once you have instructions to draw one prototypical arrow, you can use the scale3d, translate3d and rotate3d functions to reshape it and move it. I've never found such arrows very visually pleasing, but if you do find a way to draw nice ones, please post the code here.
