GCD.5 - Random Forest

Sample R code for
Random Forest.
Completely unsupervised random forest method on Training data with ntree = 200 leads to the following error plot:
Importance of predictors are given in the following dotplot.
which gives rise to the following classification table:
With judicious choice of more important predictors, further improvement in accuracy is possible. But as improvement is slight, no attempt is made for supervised random forest.
