[R] Adding average into a matplot?

[-Halcyon-]

Hi all,


I have a matrix which is filled with simulation results for several years.
Example of an output (7 years, 4 simulations):

     [,1] [,2] [,3] [,4] 
[1,]  500  500  500  500  
[2,]  516  519  509  508  
[3,]  559  573  556  566  
[4,]  613  650  611  633  
[5,]  676  714  667  716  
[6,]  751  808  742  809 
[7,]  816  890  823  879  

My matplot gives me 4 lines, but I would like to add a line with the
averages of each year for all simulations. Can anyone help me with this?

Thanks in advance!
