Adjust plot title (main) position

Question

I have been unable to find a way to adjust the (vertical) distance between plot and main title in R using par. In this example:

plot(1, 1, main = \"Title\")
         


        

Answer 1

To summarize and explain visually how it works. Code construction is as follows:

par(mar = c(3,2,2,1))
barplot(...all parameters...)
title("Title text", adj = 0.5, line = 0)

explanation:

par(mar = c(low, left, top, right)) - margins of the graph area.

title("text" - title text
      adj  = from left (0) to right (1) with anything in between: 0.1, 0.2, etc...
      line = positive values move title text up, negative - down)
