[R-pkg-devel] Problem with loading package "devtools" from CRAN.

[Rolf Turner]

Well, I just uninstalled the devtools that I had installed from github
and ran

   install.packages("devtools",lib="/home/rolf/Rlib")  
 
No error message this time; the install went just fine.
The explanation may lie in the plethora of packages that I re-installed
when I invoked

   remotes::install_github("r-lib/devtools",lib="/home/rolf/Rlib")

This probably relates to Simon Urbanek's advice to re-install all
packages in my local library.  Which I will make sure to do in future.

Previously I got an error message from

    install.packages("devtools",lib="/home/rolf/Rlib")  
 
but now of course I cannot reproduce it.

Sounds promising, but I cannot follow what "r2u" is actually
all about.  What *is* r2u?  And how do I go about using it?  Do I
invoke it (or invoke something) from within R?  Or do I invoke
something from the OS?  E.g. something like

sudo apt-get install <what???>

???

I have downloaded the file add_cranapt_jammy.sh and executed

   sudo sh add_cranapt_jammy.sh

which seemed to run OK.  What now?

cheers,

Rolf
