Is anyone on this list using SJava or any R/Java connection?
Not only is
the JTS Topology Suite that Tim just mentioned interesting,
but so is the
upcoming GeoTools2 at http://www.geotools.org/. Both are
likely to be used
quite a lot, and thus probably well-maintained.
At the recent Association of American Geographers meeting,
Frank Hardisty
asked me about this, and while I was able to install SJava (from
http://www.stats.ox.ac.uk/pub/RWin) on a Win XP laptop, we
were not able
to see how to get Java within R to see GeoTools in its
classpath. Both of
these Java resources are potentially useful, and R opinions
two or three
years ago, that Java is slow, may need revision given increased machine
capacity. I feel we could benefit from mobilizing Java insight
(but I feel
personally Java-challenged!).
I believe that Duncan Temple-Lang was playing with/working on object
discovery - this could be very relevant in terms of matching
R-internal
object representations with those in existing software that we
could - if
SJava worked - link to. I also think that we could ask him for
advice if
we discussed it first here. What do others think?
