I'm just going to elaborate on /Applications...

GUI (Cocoa/Carbon) apps must be in the /Applications tree or a bad =
things happen=20
(an exception is made for /Developer, but most people don't use/know =
about that). =20
For any other apps, like command-line tools or X11, Mac OS X doesn't =
care where you put them
and it doesn't matter.  Command-line tools are generally in /usr/local =
unless they
come with a GUI app which means that they are in a bundle like =
wine/winepath.  So,
there is no standard place for DarWINE, but most likely it will be found =
in /Applications.
That's the directory that has the correct permissions for installing =
system-wide apps
and where everything else is going to be put by habit.  Similarly, when =
you install
WinBUGS it tries to place it on your C: drive.  However, if you do that, =
then no one
else will be able to use it.  So, you choose z:\Applications\WinBUGS14.

WINE and WINEPATH arguments can be NULL and findUnixBinary() in=20
R/wineutils tries to find corresponding binaries. Can you copy the=20
following (slightly modified findUnixBinary()) into your R. I would like =

to know which command has not been found on mac, is it either which or=20
locate.

findUnixBinary <- function(x)
{
   ## --- Environmental variable ---
   cat("env\n")
   tmp <- Sys.getenv(toupper(x))
   if(nchar(tmp) !=3D 0) return(tmp)
   ## else

   ## --- Standard place ---
   cat("/usr/bin\n")
   tmp <- paste("/usr/bin", x, sep=3D"")
   if(file.exists(tmp)) return(tmp)
   ## else ...

   ## --- Which ---
   cat("which\n")
   tmp <- system(paste("which ", x, sep=3D""), intern=3DTRUE)
   if(length(tmp) !=3D 0) return(tmp)
   ## else ..

   ## --- Locate ---
   cat("locate\n")
   tmp <- system(paste("locate ", x, " | grep bin/", x, "$", sep=3D""),=20
intern=3DTRUE)
   tmp <- tmp[length(tmp)] ## keep only last hit
   if(length(tmp) > 0) return(tmp)

   stop(paste("couldn't find", x, "binary file"))
}

findUnixBinary(x=3D"wine")
findUnixBinary(x=3D"winepath")

How do you install WinBUGS on Mac? Do you choose /Aplications folder or =
...

I just want to be sure that /Applications is a safe default as=20
C:\Program Files is on MS Windows.

Additionally, how can we know if R is running on Mac? I guess that

.Platform$OS.type has value "unix" as for Linux/Unix.
