[R] Expressions and Functions

[Erin Hodgess]

Dear R People:

When the D function is used for a symbolic derivative,
an expression is returned, which is fine.

How do you change that expression to a function, please?

I've been experimenting with substitute and deparse, but no success
yet.

This is R 1.8.0 for Windows.

thanks in advance for the help!

Sincerely,
Erin Hodgess
