[R] checking bivariate normality

2010-04-06 Thread arindam fadikar
x - iris$Sepal.Length[1:50]/iris$Sepal.Width[1:50] y - iris$Petal.Length[1:50]/iris$Petal.Width[1:50] I want to check whether (x,y) follows a bivariate normal distribution or not, using density plot or scatter plot. Is it possible to plot a bivariate density in R. I cant find any. Arindam
