I do not know whether it is a good idea to add r-sq to title, but it can be done as:

sysuse auto
reg mpg price
local a = int(e(r2)*100)/100
twoway (scatter mpg price) (lfit mpg price), title(" title blah-blah, r-sq =0`a'")

best,
sasha

I have produced a twoway scatter plot to which I have fitted a linear
prediction plot using the lfit option in Stata 8.

However, I would also like to present the correlation coefficient (r) on
this graph.

Can anybody help me with this?

Thanks

Oliver
