Matthew,


My Fault I should have sent you to the current release cycle page. The link was for the old 2.6 Bioconductor release, sorry about that. :(
Personally the easies way to install any bioconductor package is to open R copy and paste the following code:

source("http://bioconductor.org/biocLite.R")
biocLite("Rdisop")
The main page for Rdisop is here : http://www.bioconductor.org/packages/release/bioc/html/Rdisop.html . This time I've given you the correct page/ current release :)

As for the rJava and rCDK. It can be difficult to install. I'm going to assume that you're on Linux as you said you tried to download the source code. In this case you want to make sure that you have your $JAVA_HOME path set. In the terminal first try:

sudo R CMD javareconf
## If that doesn't work then try

echo $JAVA_HOME
## if that returns nothing try:

export JAVA_HOME=/usr/lib/jvm/java-6-sun
This page looks like quite a good explanation : http://stackoverflow.com/questions/3311940/r-rjava-package-install-failing

Hope it helps,

Paul
