The R code will output the predictions and the fits. For the new data, these are calculated on a per trial basis; for the old data on a per condition basis. To get the R code to run, the R working directory must contain the relevant data file so that the design is known and the fit value may be calculated. Then source("new.R") or similar can be entered into the R command line (or the code can be loaded into R through other standard fashions). For all but the Forster data (for which the Monte Carlo simulation is written in R), the shared libraries (all the .dll files on Windows, the model.so file on Linux) must be in the working directory. If you are starting R on the command line, the R working directory is the current directory of the shell. If you are using the graphical interface to R, there is a pull-down menu option under "File" to "Change dir...".
