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.POSIXct(round(range(Time), "days"))
axis.POSIXct(1, at=seq(r[1], r[2], by="day"), format="%d-%b")
However the plot only shows three values 14-Apr, 15-Apr and 16 Apr, I would like to
have 24 hours marked on the x axis for each day. How can I do it? Thanks a lot!
