The message you are seeing is coming from RStudio, not from R. You can
see it here:
https://github.com/rstudio/rstudio/blob/cf5076a88a219a275a2d128191c12c1f8f4e3890/src/cpp/session/modules/build/SessionBuildEnvironment.cpp#L164-L168
It's possible that updating RStudio will make it go away; if not, you
probably have to contact them to find out why it's showing up. The R
team can't do anything about it.

Hello Duncan:
Below I am sending
(1) message from installation of a .zip file;
(2) from installation of aod from CRAN;
(3) from running the line sessionInfo()
Looks like both installations were successful despite the warning
message. Now the point seems to be to figure out why the warning arises.
Thank you.

Can someone help me understand why Rtools is needed when installing a

Please don't just repeat your post when you've been asked for
additional supporting information.

Since updating to R3.6.1., I have received a WARNING message saying
Rtools is required.
I get the same message installing online from CRAN and from a .zip
file.
It looked like installation still went through in both cases, BUT,
Another student installed a .zip file and received the following error
message:
Error in install.packages : invalid multibyte string at `<87><55>...
do I have to live with the message?
I hate to tell students to install Rtools, which they do not do much
with.
Warning message is listed below. Thank you.
