Lab 2 - Due by the end of Module 3
Complete Lab Exercise 2 in the EMC Lab Guide. For credit, you only need to answer questions that
appear below (at the bottom of this
document).
Note:
· Watch the Lab Introduction video to help you complete this (and other) labs.
· The creation of lab1_01.txt and lab1_02.txt was completed in the Dell/EMC Lab Guide in Lab 1, which we skipped, so you will need to copy/paste these files from our “Get Stuff” link into RStudio, then save them in “Lab01” so you can load them in RStudio. [Note: The “Get Stuff” area in Blackboard is within Module 0. Once in there, click on the file name, highlight the entire contents, then copy/paste into the script area of RStudio. Then “save as” to LAB01 in a local file location.]
Post all answers/screen
shots to your class Google Sites page under “LAB02”.
