Hello,
you can fit a density using MASS::kde2d and then do a contour plot
(?contour) and scatterplot your data :
x - rnorm(500)
y - rnorm(500)
require(MASS)
d - kde2d(x,y,n=50)
image(d)
contour(d,add=T)
points(x,y,pch=20)

I updated the e1071 package but still can't find
the other three arguments for plot.svm.
It's in e1071 since version 1.5-3. (current version: 1.5-4).
In addition, I can plot a
gray-colored contour region by adding the argument col = c(gray(0.2),
gray(0.8)). But I failed to change those

Hi,
I often run into this problem:
I have a data.frame with one column containing entries that are not
unique. What I then want is a subset of the data.frame in which
the entries in that column have become the 'unique' of the original
column.
Normally I program around it by taking the unique of

Spencer's solution is considerably more inefficient then using duplicated()
and subscripting: in a small example with 3 columns and 1 rows, it took
5 times as long on my Windows setup.
The reason is that aggregate() is basically a wrapper for tapply and tapply
basically loops in R.
Thanks, Bert, for the correction. Moreover, I see now that mine
