You asked to read a file, and what you told R about the file location
and name did not result in a successful operation -- in other words,
the could not be opened for R by the OS because what you tought was the
correct location ... was in fact wrong.

May be as easy as removing the second / to yield
'd:/clss2003/s151b/data/applemo.txt'
