Probabilities from survfit.coxph:
Hello: In the example below (or for a censored data) using survfit.coxph, can anyone point me to a link or a pdf as to how the probabilities appearing in bold under "summary(pred$surv)" are calculated? Do these represent acumulative probability distribution in time (not including censored time)? Thanks very much, parmee *fit <- coxph(Surv(futime, fustat) ~ age, data = ovarian)*

Re: Problems with rgl package
I also downloaded the rgl package (after reading recent Uwe Ligges' post) and installed in on my Win2k Pro sp2 machine. It seems to work with no problems.

The rgl library uses OpenGL. Is it a

OT: BibTex year-only citation in text?
Sorry for the off-topic question, but I know there are some talented LaTeX users out there. Which bibliography style gives only the year in text citations (e.g "for further details, see Anderson (1992)" )?

Question about the high dimensional density estimation
Hi, I found that the R package "KernSmooth" can deal with only 1D and 2D data. But now I have a collection of 4-dimensional data (x1,x2,x3,x4) and would like to estimate the "mode" of the underlying density. What can I do about it ?

Sweave/LaTeX Problem with EPS PDF
Dear List: I am unsure if my problem is with Sweave or LaTeX. Anyhow, I am using the MikTeX distribution and TexnicCenter. I can easily create Sweave files and all goes well until I try to incorporate graphics. I use the same code as found in the examples found in the users manual. In R, the graphics I want are created as Sweave is creating the .tex file. When I examine the .tex file
