Dear List,
I have a package that works in the context of regression models. The main
function has arguments (y, x, z, data, ...), where y is the response
variable, x is the explanatory variable and z can be other covariates.
Due to some bugs, I am interested in changing the call from (y, x, z, data,
...) to (formula, data, ...).
For instance, current usage is
myfun(y = birthweight, x = cotinine, z = age, data = mydata, ...)
and new usage would be
myfun(formula = birthweight ~ cotinine + age, data = mydata, ...)
This change would have no impact on the usage for the rest of the package.
My concern is that users updating the package won't be able to reproduce
old analyses. I.e. they would need to update the calls to myfun (but
nothing else related to the usage of other functions or methods).
I think the new usage would result in some advantages and bugs fixing and
only the disadvantage I mentioned just above.
I would appreciate advice on:
1) There could be other disadvantages for users of previous versions that I
don't see?
2) What would be the best location(s) in the documentation to explain in
detail this change?
Thanks in advance,
Jose Barrera
