Statistics, R, Graphics and Fun

TODO list:

1. paper in psychology (IJPA)
2. Michael Friendly: ancient Chinese graphics
3. an R package Sweave2 (Sweave2.lyx, Sweave2.r, Sweave2.Rnw, Sweave2.pdf) Friedrich is working on a new version of Sweave which will support us using any graphics devices.
   1. keep comments and tidy up R code: can define parse() and deparse()
   2. customize graphics function: can define graphics device (e.g. png)
   3. how to define the number of digits for numeric output in \Sexpr{}
   4. use Makevars and Makevars.win to create a symbolic link in $R_HOME/bin when installing the package from source (cf: http://www.rforge.net/pgfSweave/)
4. take a look at pgfsweave; seems more flexible than Sweave and beautiful!!
5. the 2nd Chinese R conference
   1. talk on creating R packages
   2. sponsor
   3. Martin Maechler suggested a report to “The R Journal”
   4. 3nd Chinese R conference: invitation to R core and famous useRs overseas
6. R package ISU.Stat500
   1. vignette
   2. a function to demonstrate bivariate Normal distribution (tcltk slider to control )
7. Chinese book on R graphics
   1. Hao Li suggested lattice and rgl (could also consider ggplot2)
   2. RColorBrewer should be added to the section on color selection
8. R package swfDevice:
   1. Windows build (problem in building dll’s or calling C from R?) (too difficult for me)
   2. wrap SWF in HTML output by sprintf('<object style="width: %spx; height: %spx;" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="%s" height="%s" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="src" value="%s" /><embed style="width: %spx; height: %spx;" type="application/x-shockwave-flash" width="%s" height="%s" src="%s"></embed></object>', width, height, width, height, file, width, height, width, height, file)
9. Rweb by Chris: we can create animations there very conveniently!
   1. Needs a little bit PHP & JavaScript programming in AniWiki to implement the real dynamic generation of animations without local R.
   2. What’s revised in Rweb? How to install it? Update R (and animation package) to the latest version?
10. They need assistance:
    1. Zhao L.: medical paper (to be done in the winter holiday)
    2. Shen Dai: improve price animation
11. animation package:
    1. two functions for Monte-Carlo integration in the animation package; submit animation 1.0-10 to CRAN (1.0-10 on CRAN now)
    2. Dai Shen: stock price animation
    3. improve graphics quality
    4. multivariate/high-d data
    5. jpeg2swf, png2swf, pdf2swf by Yixuan
    6. course Visualizing Quantitative Information
    7. find ImageMagick under Windows: readRegistry('SOFTWARE\\ImageMagick\\Current')$BinPath
12. COS
    1. request from COS forum: autobiography
    2. COS main site: (1) author information in the authors’ archive (2) a page template to list all authors
    3. convert phpWind to bbPress (problems: charset GB2312 –> UTF-8; SQL by Linlin Yan)
