Remote access

You can access your statistics account and run Splus or SAS or other softwares on a statistics department machine remotely.

Definitions

Local machine: a machine which you ARE using as your console and which you ARE sitting in front of.

Linux machines in Statistics: wald, dirichlet, hellinger, kiefer, savage, bernoulli, feller, robbins, hsu, sacks, wolfwitz ...

Sun Workstations in Statistics: bayes, neyman, loeve, borel, laplace, ... (all except laplace are now running Linux)

Procedures

• Case 1: Your local machine is a UNIX/Linux/Mac/PC machine running X-windows (highly recommended)

  Suppose that you already have your SSH installed. In the X-window on your local machine, type

  ssh -X loginname@feller.case.edu

  where loginname is your login name in the statistics computer network. You can change feller to any other statistics machine listed above. If you are on the Case network and your local login name and your remote (statistics) login name are same, you can simply use

  ssh -X feller

  You can then do anything on the remote machine as if it were local! For example, start Splus by typing

  Splus

  or start R by typing

  R

  Note: If you are using Splus on a Sun Workstation, type Splus or Splus5. You'll need one more step to activate a graphics window in Splus, such as

  Splus
  motif()

  There is no need to add "motif()" if you typed "Splus5".

• Case 2: Your local machine is a Macintosh or a PC that does NOT have an X-window such as cygwin, though you are still connected via ssh.

  Login by clicking Quick Connect button (for more information, see Peng's HOWTO page for PC), then you can do pretty much what you can in the statistics lab except viewing fancy graphics from the statsitics machine.

  With S+ it is possible to get mediocre graphics using

  tek4014()

  instead of motif() and you will also need to switch to tek4014 on the emulation menu in the communication software.

  In the worst case, you should be able to get some low resolution graphics by using

  printer()

  Note that you need to type show() each time you want to see a plot.

• Case 3: You run R/S+ locally on your own machine, but work with data from the stat dept

  You should be able to see all the graphics. The key now is how to transfer files and data between your local machine and a stat dept machine. For this, see the HOWTO page for PC by Peng Liu.

Remarks

1. You can find what other graphics windows that Splus supports by typing help.start()
