Dear R Plots without par arguments do start not at zero (means, the box around is somwhere outside the specified plotrange). How to start really from zero, pe. basline y=0? every standart par works like this: x<-seq(1,10,0.1) y<-sin(x) plot(sin(x)) Thanks for help Marc -- Ist Ihr Browser Vista-kompatibel?

Hi I am estimating the following coxph function with stratification and frailty?where each person had multiple events. m<-coxph(Surv(dtime1,status1)~gender+cage+uplf+strata(enum)+frailty(id),xmodel) ? > head(xmodel) id enum dtime status gender cage uplf 1 1008666 1 2259.1412037 1 MA 0.000 0 2 1008666 2 36.7495023 1 MA 2259.141 0 3 1008666

Perhaps it is my interpretation. I couldnt follow 2*min(pt(coef(summary(mod2)), 30569), 1-pt(coef(summary(mod2)), 30569)) ?? Does anyone know what I might be doing wrong or how to go about the last code? I have read as much as I...

...;'m getting distinctly non-linear scaling here. Writes: 4 disks gives me 123MB/sec. Raid0 was giving me 270/8 =33Mb/sec with cpu to spare (roughly half on what each individual disk should be capable of). Here I''m getting 123/4= 30Mb/sec, or should that be 123/3= 41Mb/sec? Using 30 as a basline, I''d be expecting to see twice that with 8 disks (240ish?). What I end up with is ~135, Clearly not good scaling at all. The really interesting numbers happen at 7 disks - it''s slower then with 4, in all tests. I ran it 3x to be sure. Note this was a native 7 disk raid-z, it wasn&...
