macOS - package installation issues

Hi
I downloaded R and Rstudio last week using homebrew. I am able to install some packages, but when I try

install.packages("faraway")

I get the following

Installing package into ‘/opt/homebrew/lib/R/4.1/site-library’
(as ‘lib’ is unspecified)

The downloaded source packages are in
	‘/private/var/folders/wp/g4z3sz4d2tvd5sx0s5r796xw0000gn/T/Rtmp5Oew8O/downloaded_packages’

I tried to install "minqa" separately as it appear to be the root of the problem, but then I got a similar error. The packages are stored as zip files in the folder shown in the last line of the R output. I would like to have the packages installed as expected in the correct folder and have the problem eradicated. Is a short-term workaround to move the zip files to the correct folder and open them there, or can this be "dangerous" in some way?

the compilation fails because gfortran system utility is absent, as a homebrew user I believe you can
brew install gcc
then go back to R and try installing minqa again

Thank you! I tried doing what you said, but quickly found this:
(gfortran support for R on macOS - cynkra)
explaining how there is an issue with gfortran for mac, but also indicate that there is not a proper solution actually :confused:

Do you know of a proper solution to the problem?
Thanks

Thats a shame, well many macOS binaries are created. look at Index of /bin/macosx/contrib/4.1 (r-project.org) which has minqa_1.2.4.tgz for R 4.1

Thanks again!
I am out on thin ice talking about this stuff so could you please explain what are binaries and what is "the other thing"?
How do I download these? Is there a way of downloading them using R or the terminal, making it efficient?

I'm not a mac user so I can only advise you so far and can't test anything out...
Here is the FAQ R for macOS FAQ (r-project.org)
on the other hand this suggests that

Unlike on other Unix systems, CRAN R for macOS installs binary packages by default

so not sure why you are getting source by default on your machine. I believe install.packages can accept "mac.binary" as an input for its type parameter

Thank you yet again!
Passing "mac.binary" to the type worked for loading the packages, but when I run

> library("faraway")

I get

Error: package or namespace load failed for ‘faraway’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/opt/homebrew/lib/R/4.1/site-library/minqa/libs/minqa.so':
  dlopen(/opt/homebrew/lib/R/4.1/site-library/minqa/libs/minqa.so, 0x0006): tried: '/opt/homebrew/lib/R/4.1/site-library/minqa/libs/minqa.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/minqa.so' (no such file)

So for me, it appears like things have been loaded, but that homebrew can't utilise the binary file or something?

It appears to be an issue with how the Monterey OS reads binary files because in the errors it says:

> mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/minqa.so' (no such file)

so I might need to turn the package into 'arm64e' or change the reading of the file to 'x86_64', but on that part, I am completely lost.

Do you understand what is wrong and how to fix it?
