Im trying to obtain a plot of given function, say the density of a
normal, in which I could indicate the area under the curve between two
points (a,b).
I.e. the P(aXb). Could anyone indicate me which is the instruction for
obtain such a shadow area under a curve?
I guess the solution is not
Try
RSiteSearch(shade area under curve)

I'm using R since version 1.6, and I didn't redefine plot in my
workspace (I would never even dream of doing anything like that), I
didn't change any R-environment variable or option in the last 4 month.
In my example x is a vector of 30 real values ...
I installed the windows service pack2

Hi Giovanna
I have encountered such problem some time ago (so it had to be R
1.8-1.9 approximately). It was connected with some complicated
plot statements and usually also with **non english** characters in
annotation texts. I did not found any traceable or repeatable
pattern and sometime it

I have matrix (n x3) that represents discrete data.
Each row of matrix is 3-D point (x,y,z). I would like
to get contour map (z value) at two dimension
(x,y). How can I use related contour function to do
this job?

Hi
library(akima)
function
contour(interp(x,y,z))
is one possibility
Cheers

Dear L Z -
Before using contour() one needs to interpolate the z values
to all points in a rectangular grid. 2D interpolation is not
trivial. The package KernSmooth (case-sensitive) will do this
for a density estimate but not, apparently, when z values are
given. Perhaps packages splines or
Have you considered interp, as in the following example:
XY - expand.grid(x=1:11, y=1:11)
XY$z - XY$x+XY$y
contour(interp(XY$x, XY$y, XY$z))
hope this helps. spencer graves

we can get point
