The OR Cases file can't be uploaded here, so just assume that is a file while writing the code using R

Challenge 5: Read "OR Cases.csv" into a data.frame. This is the data.frame that we want to use for subsequent challenges. Print the first 10 lines. Print the last 10 lines.

Challenge 6: Print the list (not the column) of dates extracted data.frame (using "$Date").

Challenge 7: The Date column is composed of strings, not dates that R will understand. Convert these to R dates. Print the first and last 10 rows.
