Hello,
Is there any function argmax in R ?
For example, if I have the vector x=c(1,4,15,7,6), max(x)=15.
But I need a function f such that f(x)=3, 3 being the number where 15 is.
Thank you very much.

I guess that you are on Windows, and that you need to install the
tools required to build R packages. The instructions for doing this
are at
http://www.r-project.org/
and then visiting the Manuals and 'R Installation and
Administration links. See especially section 3 and appendix F. This
can be
Dear R People:
in the function loess, how can one add the weight of the points which is

Hello,
Just look at the examples in ?persp.
There is a function called trans3d defined in it that will traduce your 3D
coordinates to 2D, and so you will be able to draw lines with lines function.

Dear users
I have a problem with the dr function: dimension reduction.
I give you my example, and i'll be pleased to read your comments.
