To add a picture to a plot in base R, we first need to read the picture in the appropriate format and then rasterImage function can be used. The most commonly used format for picture in R is PNG. A picture in PNG format can be added to a plot by supplying the values in the plot where we want to add the picture.
Loading png package:
Reading png file:
> Picture<-readPNG(system.file("img","Rlogo.png",package="png")) Creating a blank plot: > plot(1:10,ty="n")
Adding the picture in png file to the above plot:
> plot(1:10,ty="n") > rasterImage(Picture,5,5,7,7)
