[R] Which is better: Modifying an existing package or creating a new one?
Hi,
Given that I frequently use A, B, C, D, E packages.
In each of the 5 packages, I intend to modify one of the functions.
Two ways:
1st: Modify A, B, C, D, E to A', B', C', D', E'
Then I will use library(A') ..... library(E') instead of A, B, C, D,
E.
or Just keep the names A, B, C, D, E but modify the content
2nd: create a package F and add the five functions to the F package. For
each of the 5 functions, a line "library(A)"... or
"library(E)" is required.
Then I will need "library(F)" when I create a new program.
Which is a better way in terms of time consumption and code portability?
If I move the codes to a new computer, which way will be easier?
Any suggestion?
Thanks,
Miao

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. Best regards, ir.
