Hi all, I?m new using R. I wanto to print in a unique plot four results of four different ordinary least squares regressions. You see, I want to plot (on each box of the for parts of the graph, actual, fitted values and on the bottom the residuals). On the other side,if I only want to plot the for different residuals of each on the four estimations, how I should proceed?Thanks in advance. Imagine I have called e1,e2,e3,e4 And for titles I want to put (title) on both x axis and y axis. How should I put a main title on each graph. I hope I have explainned good. Anyway, thanks in advance for your help. -- View this message in context: http://www.nabble.com/LS-graph-tp23951942p23951942.html Sent from the R help mailing list archive at Nabble.com.
