how to suppress "S3 method overwritten" messages from being printed to user console

Question

I have an R package called ggstatsplot (https://indrajeetpatil.github.io/ggstatsplot/) which relies on a collection of packages that share a few S3 methods between each other. Therefore, every time the package is loaded, the user is bombarded with messages about this issue, which is not useful for the most users.

> library(ggstatsplot)
Registered S3 method overwritten by 'broom.mixed':
  method      from 
  tidy.gamlss broom
Registered S3 methods overwritten by 'car':
  method                          from
  influence.merMod                lme4
  cooks.distance.influence.merMod lme4
  dfbeta.influence.merMod         lme4
  dfbetas.influence.merMod        lme4

Is there something I can implement in the package internally to avoid these messages getting printed to the user's console? Maybe something using .onAttach?

Answer 1

Therefore, every time the package is loaded, the user is bombarded with messages about this issue, which is not useful for the most users.

As a "peace of mind" workaround, users can simply set the environment variable _R_S3_METHOD_REGISTRATION_NOTE_OVERWRITES_ to one of 0, no or false before loading any of the affected packages:

Sys.setenv(`_R_S3_METHOD_REGISTRATION_NOTE_OVERWRITES_` = "false")

Background: There was some instructive conversation about overwriting S3 methods becoming verbose with R 3.6 over at rlang's GitHub repo for anyone interested in more details.
