Hi Maja,
For your first question:
text(c(9,9),c(5,5),c("Sunderland","high"),
pos=c(2,4),offset=0.2,col=c("black","red"))
i.e., don't form a single string so that you can specify different
colors and positions for the two words.
For the second one, I am about to upload a new version of the plotrix
package that contains a function named "emptyspace". This tries to find
the largest rectangle on a plot that has nothing plotted within it.
