Hi baydap,
I'm not sure why the labels are coming out so close to the outer 
circumference, it may be your plotting device. I have noticed that text 
size and spacing changes quite a bit between devices. The quickest way 
out is to alter the code a bit. Change these lines:

    text(cos(c(bigtickangles,acos(c(0.95,0.99))))*1.05*maxsd,
     sin(c(bigtickangles,acos(c(0.95,0.99))))*1.05*maxsd,
     c(seq(0.1,0.9,by=0.1),0.95,0.99))
    text(maxsd*0.75,maxsd*0.8,"Correlation")

to:

    text(cos(c(bigtickangles,acos(c(0.95,0.99))))*1.1*maxsd,
     sin(c(bigtickangles,acos(c(0.95,0.99))))*1.05*maxsd,
     c(seq(0.1,0.9,by=0.1),0.95,0.99))
    text(maxsd*0.85,maxsd*0.8,"Correlation")

change the function name to something like taylor.diagram2 and source 
the new function after loading plotrix and before running your code.
