Plug-ins for the R Commander package of R: an application to calculate probabilities

Abstract

R is a prestigious software for the analysis of statistical data, and R Commander is a graphical interface of R that provides menus and facilitates its use among the non-specialized public. In this work, it was analyzed the menu options offered by R Commander for the probabilities calculation in models of random variables, and built a plug-in to improve these options for students and users who are not familiar with the properties of the variables. The programming of the plug-ins requires the Tcl / Tk programming language, which can be used through the tcltk and tcltk2 of R libraries.
