[R] looking into function body without package installation

[Olga Lyashevska]

Dear all,

I was wondering if there is a way to explore a syntax of particular  
function without package installation?
I am trying to write my own functions, and I would like to see how  
other people approached similar problems. If every time I have to  
install/load package to be able to explore function syntax I end up  
installing loads of packages I am never going to use.

I have also tried to use package 'sos' which does provide a good  
facility to find relevant information, but it seems it does not give  
any info on function body.


Thanks,
Olga
