RTable 1.0   (details) Prime ENG   153KB/86KB
The functions contained in this program use the Spreadsheet application to provide an analog of the Data Frame object in the R language and environment for statistical computing and graphics. In particular, the functions provide a means of loading a spreadsheet from a CSV file and saving spreadsheet content to a CSV file. Additional table management functions are provided, for example to add or remove rows or columns. RTable uses the RFC standard for CSV files, but you can specify changes such as a different field delimiter character (e.g. tab) or fixed-column fields. You can choose which attribute of a cell to load or save, such as name or formula, but only values are loaded correctly in this release. A small number of frame related functions are provided, like names and ncol. Comprehensive PDF documentation included.

Z LIGHTS 0.3   (details) Prime ENG   4KB/6KB
Prime's answer to mobile phone flashlights. Given that the HP Prime has no external accessible lights, this program may be of little practical use, unless the lights go out while you are using your calculator. The design aim is a compromise between maximizing the limited illumination available, and including some information that a flashlight would not (the time the light was activated).
