R help - Oct 2005 - x axis

Hello,
I write to know how can I modify the x axis : when I plot a survival object, R
plots a graph with x values = 0, 10, 20, 30 while I want a graph with values 0,
6, 12, 18, 24 in the x axis. How can I do this? In R 2.1.1 version there was
"time.inc" in survplot, but in version R 2.2.0 there isn't it!

I am sorry for my english and I hope that you understand my problem.

Thank you 
Mic

hi,

first shut down automatic axis in plot with
>plot( ...,axes=F)
then
customize your axis with
?axis 
 axis(side, at = NULL, labels = TRUE, tick = TRUE, line = NA,
          pos = NA, outer = FALSE, font = NA, vfont = NULL,
          lty = "solid", lwd = 1, col = NULL, padj = NA, ...)

you can specify what ever you want
in your case :
side=1 for x axis
at=c(0,6,12,18,24)
labels=c(0,6,12,18,24)

other way to do this with ?par : see parameters xaxp, xaxs, xaxt

best,


yves.
