assignment question 2
While solving the assignment in the second question its been asked to plot a scatter plot of imdb_rating and imdb_num_votes. I did typed plot(x = movies$imdb_rating, y = movies$imbd_num_votes, main = "IMBD rating vs imbd num votes", ylab = "imbd num votes", xlab = "IMBD rating", ylim = c(0,100000), xlim = c(0,10), col = "red") I am not getting the scatter plot instead i am getting a straight dotted line across the xaxis. Could you please help.
