R
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
See the Writing R Extensions guides for more information.
Kepler
download Kepler
wget https://code.kepler-project.org/code/kepler/releases/installers/2.0/Kepler-2.0-linux.jar 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/
