Installation

To install multiTreeR, run:

install.packages("devtools")
library(devtools)
install_github("moshagen/multiTreeR")

The Java Runtime Environment has to be installed on the target machine, get it here: http://www.java.com

Using multiTreeR

1. Define the path to an existing MPT model file in .eqn format: eqn <- 'source.eqn'
2. Either provide a data frame or define the path to an mdt: mdt <- 'source.mdt'
3. Either define the path to an restrictions file or provide a list set parameter-restrictions: restr <- list('a=g','D1=D2')
4. To run the analysis, call res <- doMT(eqn, mdt, restrictions=restr)
5. Inspect results by calling summary(res) or by peeking in the results object res$paramEst
