Hello all!
I am once again analyzing patient survival data with chronic liver disease.
The severity of the liver disease is given by a number which is continuously
variable. I have referred to this number as meld--model for end stage
liver disease--which is the result of a mathematical
I should clarify. I can generate plots for each category individually but
not for all three on the same chart.

? layout()
? par()
E.g.,
layout(matrix(c(1,2,3),1,3,byrow=TRUE) #3 plots side-by-side
Then use plot() three times to generate each of your graphs.

Have a look at
?lines
?points
?plot - the option add, add=TRUE
You will have to specify proper limits on both axes, otherwise you may
only see parts of the graphs. Some functions in the survival library
also allow stratified analyses in which case the plots account for
different strata.

Greg,
I suspect that you want something like this:
Use the 'aml' dataset and create a 'meld' column with random values from
1:25:
library(survival)
set.seed(1)
aml$meld - sample(25, 23, replace = TRUE)
aml$meld
[1] 7 10 15 23 6 23 24 17 16 2 6 5 18 10 20 13 18 25 10 20 24 6
[23] 17
, and getting
nowhere. I wish I were able to repay in some way.
Thank you!
Greg
