Thank you, Dieter:
I apologize to all of those who tried to help and who couldn't get my code to work.
I now know three things: 1) stop working at midnight; 2) always provide the correct package
name (I meant arm(), not car(); and 3) when testing code make sure you do it in a new R window.
Dieter has kindly provided a clean version of my code below with a resolution to my plotting

Please check your code in a fresh window before you submit it. There were
7 errors in your code that I almost gave up, and I am sure other people had
the same problem.
col = rep("black",length(plotdt))
col[1:24] = "red"
