Hi,
I'm going crazy trying to plot a quite simple graph.
i need to plot estimated hazard rate from a cox model.
supposing the model i like this:
coxPhMod=coxph(Surv(TIME, EV) ~ AGE+A+B+strata(C) data=data)
with 4 level for C.
how can i obtain a graph with 4 estimated (better smoothed) hazard curve
Actually what does only logical matrix subscripts are allowed in
replacement mean. I can designate columns using is.na.

Thank you! That had me stuck for quite a while and this worked like a charm!

Hi,
Try this:
dat1 = as.data.frame ( cbind ( A, B, C, D, E ) )
dat1$B[is.na(dat1$B)]-0
dat1$C[is.na(dat1$C)]-0
dat1
# A B C D E
#1 1 6 0 16 21
#2 2 7 0 17 NA
#3 3 0 13 18 NA
#4 4 0 14 19 NA
#5 5 0 15 20 25

No. Do not try this. It is a Very Bad Thing to use
as.data.frame(cbind(...))
instead of
data.frame(...)
for reasons I've mentioned before on this list. In
Hello,
What a terribly asked question.
Let me rephrase it. You have a time series 'x' simulated with garchSim
from package fGarch and have fitted a model using garchFit.
1. You want to extract the coefficients.
coef(fit)
2. You want the series of observations (simulated) and of conditional
Hi Michael,
Sorry!
You are right. That was OP's code, which I cut and paste without noticing it.
To Scoyoc:
You can also try this:
dat1 -data.frame(A, B, C, D, E )
dat1new-dat1[,2:3]
dat1new[is.na(dat1new)]-0
dat1[,2:3]-dat1new
dat1
# A B C D E
#1 1 6 0 16 21
#2 2 7 0 17 NA
#3 3 0
I think that bquote, with its .() operator, suffices for [almost?] any single
title;
don't bother fiddling with expression(), substitute(), or parse(). (You can
make
those work in many situations, but if you stick with just bquote then you can
spend your time on the title itself.)
E.g.,

Hello Thomas,
I use both svymean (with the expanded sample = people), and svyratio
(voting unit level), using the same design:
design -svydesign(id=~station + unit, fpc=~probstation+probunits,
