Align text inside a plot

Question

I am an R newbie and had a question. I am trying to place some text into an R plot. Here\'s some code using the brightness dataset in the UsingR package.

Answer 1

Try using legend() instead of text()

legend(3.5, 150, legend = c(paste("Mean =", round(MyMean, 1)),
                            paste("Median =",round(MyMedian, 1)),
                            paste("Std.Dev =", round(MySd, 1))), 
                  bty = "n")

You'll have to play around with the position adjustment. You might consider not using xy coordinates at all, but replacing those two arguments with "topleft"
