- THE R PROJECT LIST
-
- Dream, dream, dream ...
- - The Everly Brothers
-
-
- Here is a list of projects which we think could enhance R substantially.
- Some of these we re thinking about doing ourselves, but others could be
- taken on by anyone.
-
-
- o DOCUMENTATION
- Switch to a comletely SGML based set of documentation, with ways of
- producing HTML, LaTeX and Plain Text. On Windows and the Mac use
- HTML to provide a manual.
-
-
- o WINDOWS 3/95/NT PORT.
- Robert has this in hand and is nearly done.
-
-
- o POWER MACINTOSH PORT.
- This is temporarily on hold, pending funding or Ross having some
- free time. [ We have to do this. Our teaching labs are Mac based. ]
-
-
- o LIBRARY STRUCTURE
- We need a way to "attach" libraries. This should happen in
- conjunction with "save" and "load", and with some sort of hashing
- to speedup lookups in libraries.
-
-
- o MULTIPLE ACTIVE DEVICE DRIVERS.
- The basics of this is actually pretty simple to implement. The
- hard part is thinking about how to manage display lists. It would
- be nice to have a choice of "in-memory" or "disk-based" display-list
- storage.
-
-
- o MATHEMATICS IN PLOT LABELS
- We have an expression parser and can grab parse trees. All we
- need is access to font metrics for bounding boxes (done now) and
- some time to plow through a couple of appendices of the TeX Book.
- [ Ross and Paul Murrell are working on this ... ]
-
-
- o DYNAMIC GRAPHICS
- Statistics for the video game generation ...
- We need to move to an event-based model for this.
- X3d looks like it would be worth a look. It provides very fast
- response for complex wireframe structures.
- XGobi is nice too.
-
-
- o LINEAR MODELLING
- The whole "glm" suite needs to be rethought and redone.
- We need "aov" and friends (pretty easy given what we have).
- Labelling for nested specifications needs to be handled correctly.
- Additional functionality (drop1, update ...).
-
-
- o NONLINEAR MODELLING
- Was that Doug Bates I heard rustling about over there in the
- corner ... :-)
-
-
- o GAM MODELS
- The basic code is at STATLIB. Did Trevor Hastie put out an
- update to this?
-
-
- o LOESS MODELS
- The code is at NETLIB.
-
-
- o RECURSIVE PARTITIONING
- There is some very nice looking code by Terry Therneau at STATLIB.
-
-
- o TIME SERIES
- A state-space/structural models package would be nice.
- We have a partial spectrum analysis package. It needs to be
- mutivariate though.
