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 prod...

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.

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 http://www.bom.gov.au/bmrc/wefor/staff/eee/verif/verif_web_page.html.

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 Matt Pocernich NCAR - Research Applications Program 303-497-8312
