Download this List Data into your working directory and load it to your RStudio with readRDS ("LDAT.rds"). The list contains built-in air quality data, a 9 by 9 matrix, and a character vector. Please use ?airquality for the variable information. (i) Output Wind variable from airquality data. (ii) Output a subset of the air quality data containing observations from September. (iii) Output the element in the 6th row and 8th column of the matrix. (iv) Extract the matrix's diagonal elements and use them to create a square matrix. You may fill the matrix either by row or column. (v) Add one more element, 4/13/1995, to date vector, ensuring that the dates remain in ascending order. Output the resulting vector.
