Full description

An intuitive, cross-platform graphical data analysis system. It uses menus and dialogs to guide the user efficiently through the data manipulation and analysis process, and has an excel like spreadsheet for easy data frame visualization and editing. Deducer works best when used with the Java based R GUI JGR, but the dialogs can be called from the command line. Dialogs have also been integrated into the Windows Rgui.

About complexity

Cyclomatic complexity counts the independent paths through a function: 1 is a straight line, higher is harder to test. R functions only.

Release notes (0.9-2)
  • Defer JRI engine startup (.jengine(TRUE)) to first GUI use to avoid the JDK 17+ "Restricted methods" install-time warning emitted by JRI's System.loadLibrary call. Pass --enable-native-access=ALL-UNNAMED to the JVM in cases where Deducer is the package starting it.
  • Suppress stray ANSI escape codes in JGR by removing cli's cursor-show task callback and disabling cli colors / dynamic output / hyperlinks.
