Don't assume that you know what "load" means on the basis of
believing that you have an intuitive understanding of this term.
You haven't.

Read the help for load.  I.e. RTFM.  You will see that the function
load() could scarcely be *less* appropriate for what you are trying
to do.

As someone else had told, the function you need to use is source().

But how would you have found that out, without someone telling you?
Ah!  Now you're asking questions!

The simple answer is, damned if I know.  I just thrashed around for
a while with help.search() and RSiteSearch(), and looked through
  ``An Introduction to R'' on the r-project home page.  Nada.  If you
*know* the function is called "source" then you can find it.  If you
don't know .... catch 22.
