In TDMR: Tuned Data Mining in R

#*# --------- demo/demo03newdata.r ---------
#*# Given a previous tuning process with results stored in envT and saved to "demo03.RData",
#*# reload this envT, reuse the best parameter setting, train with this a  
#*# new model, using the training data in dsetTrnVa(dataObj) and predict with it
#*# on new data dsetTest(dataObj)
#*#
#*# To have "demo03.RData" available, demo03sonar.r must be run first (e.g.
#*# with demo("demo03sonar",ask=F) ).
