I guess the above function is S3. Could somebody let me know how to
show the function body in an R session?

I tried the following command. How to get the definition of, say, contrast.lm?
> methods("contrast")
[1] contrast.Design contrast.geese  contrast.gls    contrast.lm
[5] contrast.lme
> methods("contrast.lm")
no methods were found
Warning message:
In methods("contrast.lm") :
  function 'contrast.lm' appears not to be
generic
> contrast.lm
function (fit, ...)
contrastCalc(fit, ...)
<environment: namespace:contrast>
