And better than best is to use devtools to save you a fiddly
edit/build/install cycle. You don't even have to think of it as a
package, its just a folder called R with your .R files in, and a
DESCRIPTION file (metadata is always a good thing), and your functions
get attached in a separate position so they don't clutter ls(), and
load_all() will load the just the ones you've edited. Magic.

Easy peasy.

Thanks for the reply .I am able to call a simple function in an R file from
another by using source().
Now I am facing another issue .I am trying to call a r file named es.r which
have lotes of R functions.
These R functions are internally calling java functions by using ".jnew()"
and ".jcall()". I have added 
necessary jar's to the Classpath and I am able to run es.r from command
prompt .

         But when I tried to call it from anoter r file using source()
getting Exception 
Error in .jnew("com/algoTree/ClientElasticSearch/ElasticSearchLoader") :
 java.lang.ClassNotFoundException

        How can I solve this ?

Did your es.r file have an initial command that loaded rJava?
