[R] Which is better: Modifying an existing package or creating a new one?

I would consider a third option: suggest the changes to the package
authors. The authors might include your modifications to the original
package if they feel that it would improve their package.

Otherwise go for option 2. Option 1 will be harder to maintain if you want
benefit from the updates on the packages A, B, C, D, E.

than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
