R help - Mar 2005 - How to get object value in R Active memory

Dear all R-helpers,
I understand  all the actions of operation in R objects stored in the active 
memory of the computer.Could I do some opreation in active memory,what does 
the structure of active memory looks like?
for exmple : in R : a<- 2 ; capture.output(a) ; I can get the output and 
change to string,this function is written by R ,could I wrtie it in C and 
how?

Thanks in advance
Michael
