Ok. Duly noted. I'll be more concise and avoid even simple formatting

My main problem is that, if I have "gWidgetRGtk2" as an imported package,
installation on Windows from github crashes RStudio while trying to install
GTK+ libraries (although I have no ERRORS nor WARNINGS in R CMD check).
If I remove the dependency and ask users to install "gWidgetsRGtk2"
beforehand (which doesn't crash) I obviously get this WARNING:
checking dependencies in R code ... WARNING 'loadNamespace' or
'requireNamespace' call not declared from: ‘gWidgetsRGtk2’
I found out I can avoid both problems using the "pacman" package in my
Main:
if (!pacman::p_exists("gWidgetsRGtk2", local = TRUE))
{pacman::p_load("gWidgetsRGtk2")}
In this way, ‘gWidgetsRGtk2’ is installed only at first execution of my
Main, and I'm up and running.
Is this a viable solution (clearly, provided I ask permission to the user
before installing with p_load) ?
No, it wouldn't be acceptable on CRAN. You need to declare your
dependencies.
It sounds as though there's a bug somewhere, in R, RStudio,
gWidgetRGtk2, or Windows. You're in the unenviable position of having
to find and fix it. (CRAN won't care if this only affects RStudio, and
you might get away with an install that doesn't support Windows.)

Thanks in advance,

PS: better ?

No, just use
Sys.info()[["sysname"]]
and see `help(Sys.info()`. R can tell you a lot about the environment.
