vanilla session in R Gui or RStudio

As Jeff says, it might be that you have a ~/.Rprofile file with
instructions to load packages when R starts.  It could also be that
you have a .RData file, which is saved if you answer yes to:

Save workspace image? [y/n/c]: y

when you quit R.   If this file exists, then R loads it and all the
objects you had when you saved it. If there are objects associated
with packages, then that will cause those packages to be loaded when R
starts.  To avoid this, you need to move or delete the .RData file.

You can use:

startup::startup(debug = TRUE, dryrun = TRUE)

to get detailed information on what happens when R starts, e.g. if you
have a .Rprofile file and an .RData file.  That might help you to
track down what's going on.  The 'startup' package is on CRAN.

I don't know of an easy way to restart RGui or RStudio Console in
vanilla mode, similarly how you can start R at the terminal with 'R
--vanilla'.

something R normally does without your telling it to do so, but many
people forget that they have done so.

[env: Windows, R 3.6.6]

When I start R from the R Gui icon or from RStudio, I get a large
number of packages loaded via a namespace. Not entirely clear where
these come from.

As a result, I often run into problems updating packages because
something is already loaded.  How can start a new gui session with
minimal packages loaded?
