Practical Machine Learning Course Project
The goal of the project is to predict the manner in which people did the exercise. This is the “classe” variable in the training set. Any of the other variables may be used to predict with. Describe how the model was built, and cross validation used. Calculate the expected out of sample error is. Use the prediction model to predict 20 different test cases.

The below code loads the required packagesand partitions the training data set into 2 parts, test and train such that 75% of the data set is in train and 25% in test.

Final Result:
Using random forests gave an accuracy of 99.3%, hence this model is more effective than decision trees. The expected out-of-sample error is 0.7% (100-99.3).
