Hi Duncan,
Thanks for replying. I may need to clarify.
What I want is something that can let one R file in a package aware of
another R file in the same package. It does happen a lot in real life, for
example for organizing the functions into separate files, or just because
you need to include a third party provided R file containing functions.
Something alike in C you can include a file and within the same directory
by double quote and call its functions. Just wonder how R is handling this
type of include so that the included function will work even after the
package is deployed.
load the package itself will cause cyclic load error. direct source the R
file will cause complain of file not found after installation.
Thanks
