Instructions for existing R users

  • Make sure your R is updated to at least version 2.12.0
  • Open R and enter:
  • The JGR console should now be open. To load Deducer, go to 'Packages & Data' > 'Package Manager' and select Deducer and DeducerExtras.

In addition to the standard menus, upon loading Deducer, three new menus should appear named 'Deducer', 'Data', 'Analysis' and 'Plots.' These can be used to access the dialogs and data viewer. In the native GUI, the dialogs and menus work best if you use the single window (SDI) interface, which can be changed from the 'Edit'->'GUI preferences' menu item.

Load Deducer by default at start-up
