two plots on the same axis
Good morning. I wish to plot two data on the same axis. I tried plot(x,y,
type = "l") for the first and tried to use lines or points(x,y, lty = 2, col
= 4) to add or plot the second data on alongside the first. However, what I
got was not encouraging.
I have attached the two data and would be pleased if anybody could be of
help.
Thank you
Best regards
Ogbos
