Hi,
I would like to add contour lines to a (trellis/lattice-) levelplot.
Sure, there is the contour=TRUE argument, but this uses
cuts=... (which is usually chosen very high for my plots. I guess
cuts=99 is the best you can do (?)) for plotting the contour lines.
Furthermore, I do not like
HI
I have conducted a Cox analysis a frailty analysis.
I am trying to put the output into straight English.
Is this correct
- the variance explained is R2,
whereas the variance of the random effect
is the variance in R2 attributable to frailty?
Appreciated

I'm not certain what you are asking. Do you want to fit a time
series model using Bayesian Model Averaging (BMA), or do you want to
predictions with confidence intervals from a BMA fit or both? For any
of these, I suggest you start with the posting guide!
Dear All,
I have a question on overlaying a filled.contour (e.g. on soil properties data)
and contour (by elevation) in one graph. Both have the same z matrix dimension.
I'm able to overlay both graph, but the plots dimension did not overlap well on
the same plots. How can I have both

Hi all;
Thanks for the responses to my query of how to make tapply into a table
instead of an n-dimensional array. Summary of responses follows:

Besides the answers you already have, you might look at my 4D graph
example (with code) on the R Graphics Gallery:

I think it does exactly what you are asking, and therefore it might fit
your needs with only slight code
Could you walk us through, in detail, what that graph is showing?

Hi, Michael:
I'm sure the example would be clearer AND more interesting if you
used real data AND accompanied it with a description like you gave

interpretation, e.g., that if you want both z and zz less than 2, x and
