Hello,

        I would like to know if R provides the similar function to produce 
the 4-in-1 graph ("Normal Plot of Residuals", "I Chart of Residuals", 
"Histogram of Residuals" & "Residuals vs Fits") as MiniTab. If do not 
have, could anyone please tell me how to produce above-mentioned 
individual chart?

        Your help is greatly appreciated.

Best Regards,
WeiQiang Li
