R Commander is a GUI for the R programming language, licensed under the GNU General Public License. Among the existing R GUIs, Rcmdr together with its plug-ins is perhaps the more viable R-alternative to commercial statistical packages like SPSS. The package is highly useful to R novices, since for each analysis run it displays the underlying R code.

For novices, functions are one of the most intimidating features of OpenOffice.org's Calc. Newcomers quickly learn that functions are a main feature of spreadsheets, but there are almost four hundred, and many require input that assume specialized knowledge. Nor are the often circular definitions of the Function Wizard much help: You are no better off for reading that the SKEW function "returns the skewness of a distribution," for example. However, Calc includes dozens of functions that anyone can use, the most basic of which create formulas for basic arithmetic or for evaluating numbers in a range of cells.
