How to create a vertical line in a time series plot in base R?
To create a time series plot, we can use simply apply plot function on time series object and if we want to create a vertical line on that plot then abline function will be used with v argument.
For example, if we have a time series object called T and we want to create a time series plot of T with vertical line at point 5 then we can use the below given command after creating the plot −
abline(v=5)
Example
To create a vertical line in a time series plot in base R, use the following code −
x<-ts(rpois(10,5)) x Time Series: Start = 1 End = 10 Frequency = 1
If you execute the above given code, it generates the following output −
[1] 3 8 5 8 6 4 3 2 5 7
To create a vertical line in a time series plot in base R, add the following code to the above code −
x<-ts(rpois(10,5)) plot(x)
Output
If you execute all the above given codes as a single program, it generates the following output −
To create a vertical line in a time series plot in base R, add the following code to the above code −
x<-ts(rpois(10,5)) plot(x) abline(v=6)
Output
If you execute all the above given codes as a single program, it generates the following output −
