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
