Use the function 'help'

;-)

As in

 	help( "legend" )

which usefully suggests:

------------------

See Also

[...] text for more examples of math expressions.

------------------

in addition to providing examples of how to use math expresisons in 
legend()

Following the suggestion under 'See Also', one find more examples of how 
to use math expressions as well as this:

-----------------
See Also

[...] plotmath for details and more examples on mathematical annotation.

------------------

The advice in the posting guide, which you are asked to read before 
posting to r-help, says:

 	Read the online help for relevant functions

to which I might add, run and examine the examples.

e.g.

 	example( legend )

 	example( text )

etc.
