lattice.device in loop
Hi,
I am having problems creating a pdf file of a lattice graph. Things work
fine for a single image, but I am having trouble using the commands in a
loop. To illustrate by example
This works with both ps and pdf files.
dat = list(x= 1:10, y = 1:10)
trellis.device(postscript, file = "/d1/pocernic/test.ps")
xyplot(y~x, data = dat)
dev.off()
This does not. It produces a very small, non working output file.
for(i in 1:1){
trellis.device(postscript, file = "/d1/pocernic/test.ps")
xyplot(y~x, data = dat)
dev.off()
}
Really, I would like something like this to pr...

netcdf
...on, I am wondering if this might be due to a
difference between netcdf version 2 and more recent netcdf format? I've
tried using different values for the count option without luck. I have
had success reading this file into matlab.

Survey of ROC AUC / wilcoxon test functions
Hi,
I was lately debugging parts of my 'colAUC' function in caTools package, and
in a process looked into other packages for calculating Areas Under ROC
Curves (AUC). To my surprise I found at least 6 other functions:
* wilcox.test
* AUC from ROC package,
* performance from ROCR package,
* auROC from limma package,
* ROC from Epi package,
* roc.area from verification

verfication package announcement
...tten in general terms to be
applicable to other fields of study. Functions include
receiver operating characteristic curves
attribute diagrams
reliability plots
spatial scale and frequency plots
conditional quantile plots and more.
Suggestions and comments on the package can be directed to me at
pocernic at ucar.edu. More information on verification (with a somewhat
meteorolgical perspective) can be found at

lattice variable by page
...Using lattice's xyplot, is it possible to specify a variable to group
plots by page. For example, if I have
xyplot(y~x|A*B*C)
could I get a page created for each unique value in
variable C ? I am hoping to avoid having pages with the same strip above
each plot on a page.
Thanks,
M
