R: how to add the value of a variable in the title of the plot

Question

I am generating some plots in R and want to put the value of a variable in the plot's title so that I can differentiate plots. If I put the variable name in the argument "main," it does not show its value. How can I put the value of the variable in the title of the plot?

Answer 1

You can use the paste() function in "main" to show the value of the variable instead of its name.

Here is an example to show the value of variable "v":

scatter.smooth(x,y, main=paste("Value of the variable is", v))
