Specifying relative position of text in a plot
Tom La Bone asked:
What is the simplest way to specify the location of text in a scatter plot (created using the plot function) in relative terms rather than specific x-y coordinates? For example, rather than putting text at (300,49) on a plot, how do I put it 1/10 of the way over from the y axis and 1/2 of the way up from the x axis? Thanks.
See the help of par: ?par Namely: plot(rnorm(100), rnorm(100)) pu <- par()$usr x <- pu[1] * 0.5 + pu[2] * 0.5 y <- pu[3] * 0.1 + pu[4] * 0.9 text(x, y, "the quick brown fox jumps over a lazy dog") Alberto Monteiro
