How to install the server version of rpad
Hi,
How can I install the server version of rpad on a website. I have read
the instructions in http://www.rpad.org/Rpad/ServerNotes.html, but
could not figure out how. Do I have to have something like Apache on
the website? Is there any instructions in addition to those on
http://www.rpad.org/Rpad/.
Thanks,

I'm rather mystified by a similar problem and wondering whether I've
overlooked something obvious. I'm running with latest versions of R and
all packages, and latest version of JAGS running under Windows 7.
Here's the problem. I have some source code. It's given below -

rjags installation trouble
Trying to install latest rjags (3-5) from CRAN with JAGS 3.2.0
installed on Ubuntu 10.04, with r-devel ... the bottom line is that it
fails while loading with
/libs/rjags.so: undefined symbol: _ZN7Console15checkAdaptationERb
Has anyone else seen this or is it a glitch somewhere in my system?
thanks

problem with rjags installation in ubuntu 14.04
Hello folks
Earlier versions of jags and rjags installed on my system without any
difficulty, but I'm having trouble with jags version
4.3.0-1ubuntu2~ubuntu14.04.1~ppa1 (from Michael Rutter's R ppa) and
rjags version 4.6.
The call to install.packages() I always used successfully now produces
the error "cannot link to JAGS library in /usr/lib/x86_64-linux-gnu."?
