Details

ll{ Package: YaleToolkit Type: Package Version: 3.2 Date: 2010-04-23 License: GPL version 2 or newer } See individual help files for more information about the functions barcode(), gpairs(), corrgram(), whatis(), sparkmat(), sparklines(), sparkline(). The package also includes three data sets. For more information, please see the help files for NewHavenResidential, Leaves, and YaleEnergy. Non-default options to these functions may need debugging and further development, and we maintain our ``todo'' list here: ll{ gpairs(): xylim can cause cropping (or clipping), which fails to work with barcode. This difficulty with rotation and clipping is documented in viewport, and might be fixed in the future. Alternatively, we could hardcode the barcode rotation. gpairs(): more Friendly (2002) options to corrgram; without support for ellipses in grid, we're tabling this for the moment. passim: make use of single and double quotation marks consistant. } Version 3.1 is the second (beta, if you will) version released to CRAN. Please get in touch with us if you note any problems. Note that some terminology from Paul Murrell's grid package is used throughout the documentation. Users unfamiliar with grid concepts should probably look at unit before reading our help files.
