Difference between ggplot and scatter plot
I have two doubts..Would be grateful if you could clear that..1) what is the difference between ggplot and a simple scatter plot which we plot through plot command ? Whats the additional advantage we have over using ggplot instead of a scatter plot ?2) When we want to plot two graphs together..it has to be one plotted through plot and other through line ? Thanks

outcome is different by typing command.
when we make 2 graphs in one plot, the 2 plots sin and cos with their name appears; but I can only see sin name without cos name even after typing correct command. My plot names are not completely visible.
