createDataPartition notes
# the behavior of the createDataPartition() operation is a little
# counter-intuitive - you're actually manipulating the the following command
# will select the index according to seaflow$pop, and store them in the vector
# trIndex
trIndex <- createDataPartition(foo$pop, p = 0.5, list = FALSE)
# then use the vector trIndex to split the data into training data frame and
# testing data frame.
trainDF <- foo[ trIndex,]
testDF <- foo[-trIndex,]
