Getting to the command Prompt FAST in CART, MARS, TreeNet, and Random Forests

This is a very short post but it could be very useful for the expert user. As you know, Salford data mining and predictive modeling tools produce both pretty GUI (Graphical User Interface) displays of the results and also classical, plain text output. The plain text shows up in the "Classic Output" window and it can occasionally be very convenient to issue commands directly from this window. But you need to get to the bottom of the window and activate the command prompt. To do this instantly no matter where your cursor is positioned in the Classic Output window simply click (maybe repeatedly) on the "Command Line" icon on the toolbar; as soon as you see the command prompt displayed at the bottom of the window, you can type commands directly.

 

The red arrow in the screen shot below points to the toolbar icon that will toggle the command prompt on and off. Here I decided to capture a screen from a real world analysis I was running for a client; you can see that we were using TreeNet to predict a continuous outcome.

Clicking on the command prompt outcome and then switching to the Classic Output window got me to this screen with my cursor positioned next to the command prompt that is now waiting for your keyboard input.

I usually apply this trick to access plain text HELP which is both concise and very fast to display. But, of course, you can type any commands from the command prompt. I should also point out that this NOT the ideal way to issue commands to the Salford data mining and predictive modeling engines. Usually we recommend using a Salford Note Pad, as this separate window is much easier to manage and edit. But interacting at the command prompt occasionally has its uses. For further discussion of command files please check the index for our blogs and the trust manuals. The manual for each product comes with a discussion of the command language and how to control the data mining engines with commands.
