public R packages

  • ggplot2 simplifies graphical data visualization and presentation
  • coda tools for analysis of mcmc chains
  • randtoolbox has function for generating pseudo-random samples; the halton() function produces a pseudo-random over-dispersed matrix that I use to sampling from the distributions of ~20 parameters used in ensemble runs of the ED2 ecosystem model.
  • adimpro for image analysis
##example R code for extracting jpg to N x M x 3 matrix
##much slower than Matlab imread()
a <- read.image('file.jpg')
b <- extract.image(a)
red   <- b[,,1]
green <- b[,,2]
blue  <- b[,,3]

Custom R packages

Installing JAGS

1. download the file

 wget http://www-ice.iarc.fr/~martyn/software/jags/JAGS-<version>.tar.gz 

2. unpack the gzipped file

 tar xvfz  JAGS-<version>.tar.gz

3. change directory to folder with unpacked JAGS files

 cd JAGS-<version>

4. Run configuration file to check system and set system dependent variables

  • optional, for consistency with the ebi-forecast and ebi-cluster servers: include the --prefix=/usr/ to specify JAGS install location, /usr/ is default on Red Hat, which runs the ebi-forecast server but /usr/local/ is the default installation folder on Ubuntu, so --prefix=/usr/ is required when installing on Ubuntu to mirror Red Hat.
 ./configure --prefix=/usr

5. build program


6. install (requires root access)

 sudo make install

7. remove files no longer needed after installation

 make clean
cd ..
rm -rf JAGS-<version> 
Specific Code for JAGS version 2.1.0
wget http://www-ice.iarc.fr/~martyn/software/jags/JAGS-2.1.0.tar.gz 
tar xvfz  JAGS-2.1.0.tar.gz
cd JAGS-2.1.0/
./configure --prefix=/usr
sudo make install
make clean
cd ..
rm -rf JAGS-2.1.0
Installing Jags packages (rjags and R2jags) in R
wget http://cran.r-project.org/src/contrib/R2jags_0.01-26.tar.gz
sudo R CMD INSTALL R2jags_0.01-26.tar.gz
wget http://cran.r-project.org/src/contrib/rjags_1.0.3-11.tar.gz
sudo R CMD INSTALL rjags_1.0.3-11.tar.gz


Kelper project homepage

download Kepler

wget https://code.kepler-project.org/code/kepler/releases/installers/2.0/Kepler-2.0-linux.jar

follow the instructions to install Kepler, if installation does not begin, double-click on the file

after installation, to use mysql with Open Database Connection actor, may need to download jar file for jdbc java connection

wget http://www.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.13.tar.gz/from/ftp://mirror.anl.gov/pub/mysql/
tar -zxf mysql-connector-java-5.1.13.tar.gz
cp mysql-connector-java-5.1.13/mysql-connector-java-5.1.13-bin.jar Kepler-2.0/
