Task: Data Frame Creation 1. A pepper enthusiast puts together the following data set about different peppers (least spicy to most spicy), how hot they are, and how many days it takes to grow the pepper plants from seed. Pepper is the name of the pepper, Scoville Units is how hot the pepper is in thousands (the larger the number, the hotter the pepper), and Growing Time represents how many days on average it takes to grow the pepper from seed. Pepper Scoville Units (thousands) | Growing Time (Days) Bell Tabasco Ghost 0 50 855 75 80 120 (a) Create a vector called pepper consisting of the words Bell, Tabasco, Ghost. (b) Create a vector called scoville consisting of the Scoville Units as numbers. (c) Create a vector called days consisting of the Growing Times as numbers. (d) Combine these three vectors to create a data frame called HeatScale. (e) One of the hottest peppers in the world is the Carolina Reaper. The Reaper has a Scoville Unit (in thousands) of 2000, and a growing time in days of about 95 days. Create a vector called cr consisting of these values (pepper, scoville, days). (f) Add cr as a row to HeatScale. Make sure you work with the data frame you previously created, and not the original vectors. (g) Determine the variable type of each variable in HeatScale and describe any issues, if any, you observe. Include any code used and include your values as a comment. (h) Convert each variable to an appropriate type (numeric, character, factor, or ordered factor) within the data frame. For each type you choose, explain why you picked that type. Include your values as a comment in your code.
