Can someone help me understand why Rtools is needed when installing a
package from CRAN, and from a zipped file? What's the point?

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.

WARNING: Rtools is required to build R packages but it is not
