I found that the commands in my script have to set res@tmXBMode = "Manual", but "warning:ManualComputeMajorTickMarks: The precision specified is smaller than the precision needed tick mark labels may not be correct" still showed up though tmXBLabels and tmXBTickStartF are consistent. I am not sure what the warning means. Tingting's commands can be used in res@tmXBMode = "Manual" or "Explicit" without any warning. But, I only need years on x axis.
