$4.$ Import the $$Veg Data $2016.$csv$.$ This is similar to a previously used data frame but is in the correct format. Each line of data represents a trap point in the woodlot. The Station column provides the Line as a letter and the trap number. Create a plot of the relationship between the number of Non$-$Hardmast trees and the number of Hardmast trees for each trap line separately. Use different $$panels$$ to separate the trap lines. Modify both axis labels and the background. Show your code. To create these graphs you will need a new column that contains just the Line letter from each Station. $[$HINT: You will need to look up a function to isolate part of a character string$]$
