Frank,

I am (happily) using Design on Windows XP, R-2.5.0.

I do get some warnings like this:

         use of storage.mode(x) <- "single" is deprecated: use mode<- instead

but functionally all seems fine.

R version 2.5.0 (2007-04-23)
i386-pc-mingw32

locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United
States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

attached base packages:
[1] "splines" "stats" "graphics" "grDevices" "utils" "datasets" "methods" "base"

other attached packages:

    Design survival Hmisc acepack   "2.0-12" "2.31" "3.3-1" "1.3-2.2"

Evidently, this one was built a while back:

Built: R 2.3.0; i386-pc-mingw32; 2006-04-24 23:47:48; windows
