How to look into the asterisked function?

Thanks Jim and Henrique for your replies. I would like to know why some
particular functions are asterisked? What is the pros and cons while making
a typical UDF asterisked? How can I make a typical function asterisked? For
example print.anova() is not asterisked however print.acf() is. How can I
make print.anova() asterisked? 

Thanks and regards,

You can also use:

getAnywhere("functionName")

Hi friends, there is methods() function to see the all available 
methods for a particular function, for example:

head(methods("print"))

[1] "print.acf" ? ? "print.anova" ? "print.aov" ? ? "print.aovlist"
"print.ar" ? ? ?"print.Arima"



In this list, there are some functions which are asterisked like 
print.acf(). How can I see the contents of those function?



Thanks and regards,
