Dear Kingfisher,
Try this.
X <- as.matrix(read.table(textConnection("
500 500 500 500
516 519 509 508
559 573 556 566
613 650 611 633
676 714 667 716
751 808 742 809
816 890 823 879")))
Year <- 2000 + 1:7
matplot(Year, X, type = "l", pch = 3, col = "grey")
lines(Year, rowMeans(X), col = "red", lwd = 2)

Subject: [R] Adding average into a matplot?
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!
