Use cbind, or use ts.plot. Examples:

data(nottem)
ts1.ts <-  window(nottem, end=c(1936,12))
ts2.ts <-  window(nottem, start=c(1930,1))+15
plot(cbind(ts1.ts, ts2.ts))
plot(cbind(ts1.ts, ts2.ts), plot.type="single")
ts.plot(ts1.ts, ts2.ts)  # same as above

See help on plot.ts and ts.plot

Hi, I have a simple question regarding plots of time series. I 
have two time series, say ts1.ts and ts2.ts. They are both monthly. 
The first one ranges from 1944:2 through 1999:7 whereas the second 
one ranges from 1974:1 through 1993:6. How can I plot both of them 
in the same plot (the shorther series would be only displayed in a 
section of the x axis since it is shorter). 

My naive try was 

plot(c(ts1.ts, ts2.ts), xlab="time", ylab="")

but it did not work. Note: I have defined the two series as 

ts1.ts <- ts(series1, start=c(1944,2), frequency=12) # 234 obs. 
ts2.ts <- ts(series2, start=c(1974,1), frequency=12) # 666 obs. 

Thanks a lot in advance. Best, Francisco. 

PS: I am using R for Windows and R for (Red Hat) Linux version 
1.0.0.

If a train station is where a train stops, then what is a workstation?
