I'm trying to explore R from J, and I'm having problems. I've tried the
batch mode once in the past, but I want something better. I was
initially interested in Rserve, but
http://www.rforge.net/Rserve/doc.html indicates that's not such a good
idea on Windows. (Actually, it seems to suggest I not use Windows
rather than I not use Rserve. Would that I could change! :-)
It didn't work for me, anyway, but I won't go into that unless someone
is really curious.
So I tried the DCOM server. I've got an up-to-date J, and PacMan says
everything is current.
I installed rcom on R with install.packages("rcom"), as instructed. I'm
running R 2.4.1, FWIW. Then I tried the installation instructions on
http://www.jsoftware.com/jwiki/Interfaces/R/DCOM.
Step 1 worked, but step 2 didn't:
,----
| load'stats/r/rdcom'
| '' conew 'prdcom'
| |domain error: wd
| | wd'cc w oleautomation:StatConnectorSrv.StatConnector.1'
|
`----
That's on a fresh J session. I'm not familiar enough with Windows
programming or OOP in J to know exactly what path to try next.
I did seen that Kamakura-san posted a note back in April about rdcom,
but I don't see any replies. From his note, I gather it works (he did
get a result from conew), and I gather there may be problems doing
graphics in R instead of pulling data back and doing them in J (J has
good graphics, but I'd hate to reinvent the wheel if an R package
already had what I happened to need).
Any tips?
TIA,
Bill
