Here's an example:
We define a function to run a simple GLM in R.
RserveExample=: 3 : 0
rdcmd_rserve_ 'x<-c(1,2,3,4,5)' (1!:2) 2
rdcmd_rserve_ 'y<-c(8,21,31,38,50)' (1!:2) 2
rdcmd_rserve_ 'modelfit<-glm(y~x, family=gaussian(link=identity))' (1!:2) 2
if. y do. rdget_rserve_ 'capture.output(
When I try a new project on Windows the path offered for the new project is
~C:/Users/DanB2/j64-802-user/
the ~ should not be there

That should have been expanded from ~user. What the values of the nouns
SystemFolders_j_ and UserFolders_j_ ? Please also post your JVERSION .
Thanks.

This example works fine for me, see session below. Tested on J802, linux64,
R 3.02.
What versions of R and J are you running, and what OS?

I'm running both J801 (Jqt64) and 64-bit J602, on 64-bit Windows 7.
If I could get the debugger to work with J801 I would use it all the time.
That's another issue I could use help with! It just doesn't work at all, or
perhaps I simply don't know how to invoke it properly. The new editor works
Please also give us the version of R.

Ok. I downloaded J8.02, installed ALL packages, and ran my little Rserve
example program. It (mis)behaved exactly as before.
Then I uninstalled R, restarted my computer, deleted the R folder from
C:/Program Files, downloaded R, and installed it from scratch. Now my example
runs just as it shou
Good news, thanks.

Do you mean installing a new version of J? I really don't think this is
necessary. Installing or uninstalling J does not touch anything related to
R.
Most likely something went wrong with your R installation
the debugger is still in JHS,
you may find these utilities useful. They need to be in z in order to be
accessible while debugging.
dbg 1 is on, dbg 0 is off, and switches back to base locale.
dbgs '' gives a stack trace
dbgss 0 1 2 3 will provide the local variables for the top 4 procedures o
the debug package should work in all environments including jqt, jhs and
jconsole.
load'debug' NB. this may not be needed
dbr 1 NB. start debuger
when it enters suspended mode, use various db... verbs, eg
dbctx'' NB. show the context

I get with exp, this

is there a way to define exp such that it does not return imaginary number

Nevermind, I see you answered yourself.

The conference was a success.
Speakers: please provide materials as appropriate to JoJ.
After a period of recovery (it is a hard work), I assume we'll start
thinking about what to do better and different in 2016.

Thanks for the great conference. The variety of presentations is important.
Everybody using J has a interesting story to tell. Those who had not
presentation would be potential for the next conference.
