Show me the the code in R Programming language.
Import the sp.csv file.
Question a: Calculate the correlation between daily Adjusted Close (`Adj Close`) and the Volume.
Question b: Create a new variable return, defined as the percentage change of a day's Adjusted Close compared to last trading day's Adjusted Close. That is, return(t) = 100* (Adj Close(t) - Adj Close(t-1))/Adj Close(t-1).
Calculate the five number summaryof the return using the summary() function.
Hint: The easiest way to get the previous trading day's Adj Close value is using the lag() function in the tidyverse package. Import the package first before using the lag() function.
