Note about R-studio Assignment (Week7)

For this week, the assignment and instructions are combined into the one rmd file.  You will need to download R and R-studio, and then you will be able to open the .rmd. You will need to know where you saved the frogs.txt file, navigate to its location in the files section of R-studio, and set the folder as the working directory.For the submission you can either edit the rmd, change the name and submit it, or you can create a new script, copy and paste the questions and answers into it and submit that, or you can copy and paste the code and output of the code into a word doc.
