I collected some data (under Windows XP). On a modern desktop, running R from a CD-R or from a USB 2.0 thumbdrive was perfectably acceptable, with startup times of about 5 secs and little delay when running. On a 2.5year old laptop with a USB 1.1 port (but the same thumbdrive) it took about 15secs to start and with frequent delays the first time an object was used -- I would not find that tolerable. The laptop's CD drive was slower than the desktop and there were delays when it powered down, but it was acceptable. This was less performance penalty than I was expecting, and less than I have seen on a high-latency network file system. So it looks as if all we can do is trade a slower startup time (by caching files) for removing hiatuses when running. (Caching the pkg.rdb and pkg.rdx files when a package is opened would probably only take up a little over 1Mb in a typical session.) Writing to the thumbdrive took about 20mins, as R has so many small files and the drive has a VFAT file system. -- Brian D.

RE: [R] Running R from CD?
Dear Jari, When I distribute an R Windows CD/ROM to students, I generally include both the installer and an installed version. This allows students who don't want to or can't install the software to use it. They pay a big penalty in speed, however. A flash drive would provide better performance if this is a viable option. It's not really necessary to do anything as elaborate as in my Rcmdr instructions if the CD is for one's own use: Just install to the CD (copy over installed versions of whatever contributed packages you want to use) and run rgui.exe from it.

Re: [R] Running R from CD?
Let's be a little careful here. An R for Windows installation is relocatable, so you can just install it into a temporary directory and burn a copy of that onto CD. (That may not be true after installing packages into a non-default library.) It is not true of a Unix or MacOS X installation, as far as I am aware, for they have absolute paths coded into the files. However, an R session does need to be able to write to a temporary directory, and also needs a `home' directory and at a last resort the latter defaults to the current directory. So you do need to be running on a machine on which you have a writable area. A policy that says you cannot install a program, but you can run from a CD and you can let such a program write to your area seems full of holes to me. (Ours does not allow low-privilege users to run programs from a CD.) Also, many organizations ban the use of USB drives for security reasons. BTW, I believe running R 2.0.x from a CD will be a lot slower than 1.9.1 because of lazy loading and frequent file accesses: that's a theoretical issue we intend to address for 2.1.0, but not one anyone has yet commented that it is a problem.

RE: [R] Running R from CD?
I have noticed that R 2.0 did run slower than I thought it should. It's only now that you've raised the issue that I realise how much slower. However since I only use the CD when I am working on other people's machines I can't really say if there are other factors impacting upon the performance. I'll dig up the old disk, make some comparisons and forward the results. The bottom line is that it is not a big issue for me.

You can simply start a Linux live distribution including R (for example bio-knoppix) from CD, but you have to restart pc with cd inside. A.S.

And of course, how to? Yes, for a suitable definition of `CD'. (You need the extensions which allow long file names and lower-case chars.) You will need some disc area where you unpack the files from the R installer. Then just write the top-level directory (rw1091 or whatever) and all its contents to CD-R. The Windows installation (but not the Unix one) is relocatable as it only uses relative file paths. -- Brian D.

Re: [R] Running R from CD?
Hi! Make a isntallation of R on a PC where it is allowed. Install all packages you need. Burn the installation folder (rw1091) on the CD. Start R by clicking on Rgui.exe in the bin folder (rw1091/bin). Or set a path on the command line to (CD drive letter) :\rw1091\bin Or create a shortcut. This should work. Hope it helps. Eryk Ps. If you need to install afterwards package you have to set R_LIBS to a writable drive. *** REPLY SEPARATOR *** On 8/27/2004 at 3:54 PM Hans van Walen wrote: At work I have no permission to install R.
