Os X Could Not Be Installed No Packages

No packages were eligible for the install. Contact the software amnufacturer for assistance. Quit the installer to restart your computer and try again.' Click to expand. If you're connected to the internet, disconnect it. Re-create the Bootable USB and try installing. Make sure you erase the drive, not the partition. OS X No Packages were eligible for install repaired “No packages were eligible for install” is a message that appears when attempting to install OS X El Capitan on older macs. MacBooks are a very popular purchase in Melbourne and around Australia so it is important to understand the reasoning behind why this message appears. “macOS could not be installed on your computer. The installer resources were not found. Quit the installer to restart your computer and try again.” This happens regardless of whether you’re performing an upgrade or a clean install, and whether the drive you’re installing to is formatted as APFS or HFS+. So, what’s the solution? No user data will be lost in this process. Resetting your PRAM will not only fix this particular OS X install issue, but it can also fix network issues, sound issues, and display issues. So next time your Mac is acting wonky, reset the PRAM and it should be back in working order.

Hi,

I'm new to R, because we're using it at Uni, and I'm having problems installing Rcdmr.

I've downloaded R 3.5.1. as well as XQuarts and the other tools CRAN told me to download, and I've even followed the step-by-step instructions (https://socialsciences.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html) written by John Fox himself, but I'm getting error an error message I don't understand:

install.packages('Rcmdr')
--- Please select a CRAN mirror for use in this session ---
trying URL 'https://cloud.r-project.org/bin/macosx/el-capitan/contrib/3.5/Rcmdr_2.5-1.tgz'
Content type 'application/x-gzip' length 5014770 bytes (4.8 MB)

The downloaded binary packages are in
/var/folders/5t/qh9jqrv550l_yjc6ly3l6d2c0000gn/T//RtmpaCDkGF/downloaded_packages

Installed

What does it mean?

I also tried installing the library after the step described above, but then I'm getting this message instead:

library(Rcmdr)
Loading required package: splines
Loading required package: RcmdrMisc
Loading required package: car
Loading required package: carData
Error: package or namespace load failed for ‘car’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘data.table’
Error: package ‘car’ could not be loaded

As far as I can surmise, in the first step, Rcmdr is put in some weird folder which then creates the error 'package 'car' could not be loaded'.

All of this is essentially me saying 'HELP'. And before you suggest I go to my professor, I've already done that, and he couldn't help me either. Just made comments about how Mac computers are stupid, essentially. So I need your help, Internet!

Os X Could Not Be Installed No Packages Were Eligible For Install

Sincerely,
A complete R newbie who just wants to use it for his statistics class
