Well, still no responses, but I'm further along the trail. I decided that I
must need that 'PACKAGES' file so I went back to CRAN and got it, and placed it

This time with 'Other Directory URL' as 'files:///Applications/tgz12.1/' I at
least got the Package list populated in the 'Repository Version' column.
I selected all and clicked 'Install Selected' to no obvious result,
although maybe I was too impatient. Then I tried again selecting
only the first package 'abc' but still it seems without response.
First of all, if you are trying to install from a local repository
there are specific and detailed requirements. See page 21-22 of the
R-admin.pdf manual under heading "Setting up a package repository".
Yes, but you don't actually need to set up a repository locally:
provided you have a PACKAGES file you can use contriburl= in
install.packages (and as I read it, as 'Other Directory URL').
You can even re-generated a PACKAGES file by cd-ing to the packages
directory and using
tools::write_PACKAGES('.', type="mac.binary")
but the advantages of using a PACKAGES file+install.packages
(installing in the right order, picking up dependencies) are bigger
for source packages and a complete local repository.
Second, there is no need to place the .tgz files in a folder in /Applications.
Also highly undesirable since /Applications is for applications and a system
folder.
I have never installed from downloaded files so I may be completely wrong.
I have tested my recipe by downloading foreach_1.3.0.tgz and doing as described
below (except that I installed the stuff in my personal R library).
Place the .tgz files (mac binary package files) in a directory in your user
tree.
For example ~/Temp/R
Start R.app and set the above directory as the working directory (menu Misc, Change
Working Directory or with setwd("~/Temp/R").
Then for informative purposes do list.files() to check if all went well. You
should see a list of the files you placed in that directory.
Now enter .libPaths() to see in which slot the main R library is
located (Look for
"/Library/Frameworks/R.framework/Resources/library"; for me it's in
slot 2).
Assume you want to install package foreach_1.3.0 (file foreach_1.3.0.tgz) then
enter the following command in R.app
install.packages(pkgs=c("foreach_1.3.0.tgz"),lib=.libPaths()[2],repos=NULL)
No c() is required for a single character string. And you normally
want to install into the first library tree, not into R's own tree,
but if you do want the latter it is simply lib=.Library.
Repeat for other packages ( you can also set pkgs=c("pkg1.tgz", "pkg2.tgz",...)
)
Or simply (untested)
install.packages(dir('.', pattern="tgz$"), repos=NULL)
good luck
