Difference between ggplot and scatter plot
Title
Question
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
