Re: [R] stars (as fourfold plots) in plot (symbols don't work)
Here are 2 useful paths (it's up to you to decide if either is the right path). The my.symbols function in the TeachingDemos package allows you to create your own functions to create the symbols. But in this case, you can just use the locations argument to the stars function: stars(cbind(1,sqrt(test[,3]), 1, sqrt(test[,3]))/16, locations=test[,1:2], + col.segments=c(gray90, gray),draw.segments=TRUE, scale=FALSE) -- Gregory (Greg) L.

Re: [R] stars (as fourfold plots) in plot (symbols don't work)
I was feeling pretty silly when I saw there was actually a locations parameter in stars, as well as axes etc. But now the problem is that the x and y axes in stars must be on the same scale! Which unfortunately makes my data occupy only a very narrow band of the plot. I guess one option would be to scale one set of coordinates and then manually change the axis labels!? But I'll have a look at my.symbols first. Thanks for the tip! Maja Greg Snow-2 wrote: Here are 2 useful paths (it's up to you to decide if either is the right path).
