Running Splus on Unix

Since Splus may be down for a while on the pc clusters, here is some info for running Splus on the unix machines. There are unix clusters at

Bio Sciences 002CC
Soc/Psyc 133
Hudson Hall 117
Teer Eng Bldg Basement

When you log on, you should have a window (or two) up that you can enter commands into.

First, type
```
 
% xterm &
```
The % sign tells us we're at the unix prompt. Remember the Splus prompt is >. This brings up an additional window. If you want more, type it again and another window will pop up. We'll use one window to run Splus and another to run an editor to save useful commands.
In one window start netscape:
```
% netscape &
```
In netscape you'll want to go to lab1 and download the necessary data. When you get to lab1 click on fish.asc and save it to a file called fish.asc. If you type
```
% ls
```
from one of your open windows, it will list all the files in your home directory. fish.asc should now be there.
Now in one of the windows start Splus by typing:
```
> Splus
```
This window now is the command window for Splus. In that window type
```
> motif()
```
This brings up a graphics window. Now you can type the Splus commands into the command line window as before.

The only difference is that reading in files is slightly different. To read in fish.asc type in Splus

> fish_read.table("fish.asc",header=T)

You should now have the dataframe fish loaded into Splus. To check type

> fish

2 lumber       1   48.7   1862  1.5 0.1760913
    :
169 wacamaw      16   45.4   1710 1.70  0.230448921
170 wacamaw      16   41.7   1255 1.40  0.146128036
171 wacamaw      16   36.0    702 0.92 -0.036212173

Now you're set to follow the directions in lab1.
In another window, you may want to record useful commands. You can open a file called notes1 by typing:
```
% pico notes1
```
This will create a file called notes1 and let you edit it using the pico editor. This is the same editor that you use in pine to compose mail messages. You can cut and paste in unix using the left mouse button to highlight text, and the center (or left and right buttons together) button to paste the highlighted text.
