Change the R code by imposing restrictions on the data. For instance, we might insert the 
following line of code at the appropriate position: 
z <- z[z[,1]*z[,2]>800000 & z[,1]*z[,2]<1700000,] 
 
Note: you can observe the entire R code in the blogged computation (below) 
 
If we select only those screens for which the number of pixels (=width * height) is in the interval ] 
800000, 1700000[ then most of the outliers are removed. In both computations the boxes (= middle 
50% of observations are not strongly affected.
