I have written code which puts text to the upper right of points on a plot. Some of my point are very close together and the new text is writing over the previous text. Has anyone written a clever "smart-text" function that writes the text in a blank spot near the point (perhaps on the lower left or lower right side) when it discovers that the new space is not blank. I could write such a function if there was an is.blank(x,y) command. Does something like that exist? Thanks.
