[R] Fwd: Re: Graph color

[Greg Snow]

What you are asking (making labels of points not overlap the points) is either very simple or very complicated, depending on your data and what you want the results to look like.

It may be as simple as text(x, y-strheight('A'), labels).

If that does not do what you want, then there is thigmophobe.labels in the plotrix package (already mentioned by Jim Lemon) which works great for some datasets.  Also spread.labels (plotrix package) and spread.labs (TeachingDemos package) work in different situations.  There may be some other automated attempts in other packages, but they are not coming to mind.  A less automatic approach that gives you more control is the dynIdentify/TkIdentify functions (TeachingDemos package).

If you want rectangles around the labels, then you may want the boxed.labels function (plotrix).  If you want to do your own rectangles then there are the rect and symbols functions.

Hope this helps,
