R scripts for multivariate analysis Files

This is the script prepared to run randomForest package from R environment in a manner of 10-fold cross-validation mode. This version is prepared to the regression tasks. For more information please refer to its original manual at the CRAN repostitory:

http://cran.r-project.org/web/packages/randomForest/index.html

It requires data prepared in a manner of 10 pairs of training-testing datasets in tab-delimited TXT files, where the last column contains the known answer to the problem (dependent variable) and previous columns are features (regressors or independent variables). The assumption is that the model is of MISO type (multiple-input-single-output)

Script basic adjustable parameters are:

m_try
# This is the number of the input variables randomly chosen for each tree during the forest building. If equal to 0 then automatic search is performed ("mtry")
max_nodes
# Maximum terminal nodes in the tree ("maxnodes"))
num_tree
# Number of trees ("ntree")

Please find an example of how to run the script in the example.tar.gz archive Runs on Linux and Mac 
Windows users must get rid of multicore library
