Hello

sorry that I did not make the letter clearly stated.

Now I have 21 boxplots (No. 1, No. 2....No. 21 from the left to the
right)(lattice).
I want the first two (No. 1 and 2) to become red and the rest (No. 3 to No.
21) to become blue.
(rep will make No. 1 and 2, No. 9 and 10, No. 17 and 18, No. become red.)

Please kindly advise R-code that can specify the red color for No. 1 and 2,
the blue color for the rest.
Thanks again.

Elaine
