Any simple way to make this happen?
...o translate it to
y <- c(1,2,3,4,1,2,3,1,2,3,4,5);
i.e. for each number in x, we need to generate 1:x and put it in y.
The program need to evaluate this type of calculation for millions of times in simulation. Is there any elegant way to make this happen without iteration?
Many thanks!!

R plot
...ts(10,-10)
The last point is missing because it is out of
range of the first plot.
I just try to switch from Matlab to R. In Matlab,
it always can automatic adjust the xlim and ylim
for such case.
Is it possible auto adjust in R? Otherwise
keep tracking xlim and ylim is really annoying.

R Plots for Recurrent Events - Suggestions are needed
...ics57.htm)
And do you have some other recommendation in visualize recurrent events?
I did some research online. Some people use ggplot2 to plot MCF, but it requires some additional coding.

Help in Lattice!
...46 30 1.5 -5.5657e-01
274 46 30 2.0 -2.1659e-01
I use
xyplot(Value ~ Visit | factor(ID), data = dataM, typ = 'o',layout = c(3,3),as.table=TRUE);
to plot each patient longitudinal observations.
How can I add dose information to each panel? e.g., adding "Dose = 30"

HELP: BRUGS/WinBUGS/RBUGS Response is a combination of random variables
Hi,
Is there anyone know if BUGS language allows the combination of variables as response
such as
Y[i] <- a*X1[i]+b*X2[i]
Y[i] ~ dnorm(c,d)
It seems doesn't work in my model. The problem is between two ######.
The error message is
> modelCheck("BayesBioMarker.BUGS")
model is syntactically correct
> modelData(paste("BUGS_data.txt",sep=""))
