The curve is made by plot(x,y). Thanks!

I have a variable named "Medicine" which has seven values in date format, on the
following plot, how can I use a red line to indicate the time when the medicine was
taken on x axis?
The following is my original plot of blood pressure vs. time.
plot(time, bloodpressure,xlab="Time",ylab="bPress"
I am trying to plot "time" variable (the time is recoded for three days at 5 minutes
interval in the format of 2001-05-14 13:45:00) VS. blood pressure. My code is the
following:
plot(time, bloodpressure,xlab="Time",ylab="bPress",main="Time VS Blood Pressure",
type="l", xaxt="n")
r <- as.P
