Cannot download "raster" package in R Studio--CodePudding

I am trying to use the raster package in R but since I bought a new computer and have the latest version of R on macOS it mentions certain packages are not available for this version of R.

I tried downloading R directly on R studio and that gave me errors.

Next I tried installing directly from GitHUB using the following command: install.packages('raster', repos='https://rspatial.r-universe.dev')

and this is the error message I receive:

install.packages('raster', repos='https://rspatial.r-universe.dev')

Installing package into ‘/Users/username/Library/R/arm64/4.2/library’
(as ‘lib’ is unspecified)
also installing the dependency ‘terra’

Packages which are only available in source form, and may need compilation of
  C/C  /Fortran: ‘terra’ ‘raster’
Do you want to attempt to install these from sources? (Yes/no/cancel) yes
installing the source packages ‘terra’, ‘raster’

When I load raster next this is what I see:

library(raster)
#Error: package or namespace load failed for ‘raster’ in #loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
# there is no package called ‘terra’

I really need the raster package urgently. Please help

Make sure you have Rtools installed on your system (click here). Then try the following steps:

1- When you open RStudio, right-click on the icon and choose `Run as Administrator.

2- Temporarily deactivate your firewall or antivirus.

3- Use the following commands:

install.packages('raster', dependencies=TRUE, repos='https://CRAN.R-project.org/')
library(raster)

See if the problem is solved.

Can you edit your question and show what happens when you run

install.packages('terra')
install.packages('raster')

I would not install from source code if you do not have to. But if you must, first install "terra". See https://github.com/rspatial/terra for instructions about installing from source code.
