Write the function find Msg Words () of Section 3.5.3. This function takes as input the message body (with no attachments) and the return value is a vector of the unique words in the message. That is, we only track which words are in the message, not the number of times these words appear in the message. This function should eliminate punctuation, digits, and blanks from the message. Consider whether it is simpler to split the string by blanks first and then process the punctuation, digits, etc. The function should convert capital letters to lower case, and drop all stop words and words that are only one letter long. A vector of stop words is available in the tm package. Use the stop words () function in this package to create the vector.
