hi all

i am having a problem with the expression/paste command

say we estimate a variable, named PHI

it contains the value of say 2

and we want to display this value as " hat(phi) = PHI" onto a graphic

i.e.	 " hat(phi)=2 "

how does one do this?

i've tried the following:

1.	legend(-5,.3,expression(hat(phi)*"="*PHI))

2.	legend(-5,.3,paste(expression(phi),"=",PHI))

but they do not work.

any help?
