I need help creating a bubbleplot, like a simple pseudo three dimensional scatterplot of circles whose sizes index a 3rd variable. I initially came across this at http://addictedtor.free.fr/graphiques/graphcode.php?graph=73 but the circleplot function does not exist in fbasic as listed in the document. _________________________________________________________________ 50F681DAD532637!5295.entry?ocid=TXT_TAGLM_WL_domore_092008 [[alternative HTML version deleted]]

The function symbols() is in the package 'graphics', so you don't
need
any add-on packages.
For example:
# similar code to the example you mentioned
set.seed(1)
symbols(x = rnorm(50), y = rnorm(50), circles = abs(rnorm(50)),
main = "Circles Plot")

I don't quite understand your R code (I think your random numbers make
the graph very hard to read!), but I have also written an example for
the interaction effect:
## 400 bubbles to show the interaction of x and z
sq = seq(0, 10, length = 20)
x = rep(sq, 20)
z = rep(sq, each = 20)
y = c(outer(sq, sq, function(x, z) 10 + 1 * x + 0.5 *
z + 0.5 * x * z + runif(1)))
symbols(x, z, y, bg = rgb(1, 0, 0, 0.1), fg = "yellow")
## observe the bubbles from the x-axis or y-axis
Regards,
Yihui
