[Rd] How to modify the start-up message

[Ron Michael]

Hi all, I got a custom R package in .zip (i.e. meant only for Windows installation). When I load that package, there are some start-up messages, probably loading through .onLoad() function. However I want to modify those messages. Please note that I do not have any other version of that package like .tar.gz fomat etc.

Having only the .zip version, is there any possibility to modify those start-up functionalities of that package?

Thanks for your help.
