R will not run on mac os high sierra after installing with homebrew dyld: Library not loaded error

Following this post I used the following steps:
brew tap homebrew/science
brew install Caskroom/cask/xquartz
brew install r
Then when trying to run R, I get this error:
dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib
Referenced from: /usr/local/Cellar/r/3.4.3_1/lib/libR.dylib
Reason: image not found
Abort trap: 6
I was able to resolve this by uninstalling and reinstalling readline:
brew uninstall readline
brew install readline

Brew: uninstalling all version of a package

I am trying to uninstall qt.
I did brew uninstall qt, and it uninstalled the version 5.9.0, but it says that:
4.8.7_2, 5.8.0_1 2 are still installed
I want to delete them as well.
Is there a way to uninstall with brew all the versions of a package?
Thanks in advance!
OS: Mac El Capitan
brew uninstall --force qt
worked
brew uninstall qt#4.8.7_2 qt#5.8.0_1
Both of these will probably warn that there are still dependencies, for example on my machine:
$ brew uninstall qt
Error: Refusing to uninstall /usr/local/Cellar/qt/5.14.0
because it is required by gnuplot, octave, poppler and pyqt, which are currently installed.
You can override this and force removal with:
brew uninstall --ignore-dependencies qt
You don't use --force, but add these reverse dependencies to the list. For my example above:
brew uninstall qt#5.14.0 gnuplot octave poppler pyqt
You can then check with brew list if there are any other remnants you want to remove.

‘seewave' install error “'sndfile.h' file not found” (for R 3.2.0 under OSX Yosemite)

When updating to R 3.2.0 I had to reinstall seewave.
I managed to install the required packages fftw, tuneR, rgl, and rpanel.
But, when trying to compile seewave I got the message:
stft.c:3:11: fatal error: 'sndfile.h' file not found
On linux it is sufficient to install libsndfile library, for example with
sudo apt-get install libsndfile1-dev
On OS X just do:
brew install libsndfile
Pisca46 - Installing via 'brew install libsndfile' helped.
On CentOS, the package has a different name :
sudo yum install libsndfile-devel
I also had to install the fftw-devel yum package

Installing R with Homebrew

I'm trying to install R using Homebrew. I ran these commands which are recommended elsewhere on SO:
brew tap homebrew/science
brew install R
For brew tap homebrew/science, I'm receiving this error:
Error: Already tapped!
For the second command, I receive this:
Error: No available formula for r
Any suggestions?
As of 2017, it's just brew install r. See #Andrew's answer below.
As of 2014 (using an Yosemite), the method is the following:
brew tap homebrew/science
brew install Caskroom/cask/xquartz
brew install r
The gcc package (will be installed automatically as a required dependency) in the homebrew/science tap already contains the latest fortran compiler (gfortran), and most of all: the whole package is precompiled so it saves you a lot of compilation time.
This answer will also work for El Capitan and Mac OS Sierra.
In case you don't have XCode Command Line Tools (CLT), run from terminal:
xcode-select --install
As of 2017 / Brew 1.3.2 # macOS Sierra 10.12.6 all you have to do is:
$ brew install r
You don't even need to tap homebrew/science since r is now a part of core formulae for the Homebrew (homebrew-core).
It will also install all dependencies automatically:
==> Installing dependencies for r: gmp, mpfr, libmpc, isl, gcc
There are two additional options you might want to know:
--with-java
Build with java support
--with-openblas
Build with openblas support
I used this tutorial to install R on my mac, and it had me install xquartz and a fortran complier (gfortran) as well.
My suggestion would be to brew untap homebrew/science and then brew tap homebrew/science and try again, also, make sure you don't have any errors when you run brew doctor
Hope this helps
brew install cask
brew cask install xquartz
brew tap homebrew/science
brew install r
This way, everything is packager managed, so there's no need to manually download and install anything.
Working on El Capitan 10.11.1, the steps I followed are
brew install cask
brew tap homebrew/science
brew install r
This is what actually worked for me on OSX Yosemite.
brew install cask
brew install Caskroom/cask/xquartz
brew install r
If you run
xcode-select --install
you do you not need to install gcc through brew, and you will not have to waste time compiling gcc. See https://stackoverflow.com/a/24967219/2668545 for more details.
After that, you can simply do
brew tap homebrew/science
brew install Caskroom/cask/xquartz
brew install r
I am working MacOS 10.10. I have updated gcc to version 4.9 to make it work.
brew update
brew install gcc
brew reinstall r
brew install homebrew/science/r
works on OS X 10.11.6.
If you meant "r" specifically:
It was migrated from homebrew/science to homebrew/core.
For r 3.4.3 Mac High Sierra:
brew tap homebrew/core
brew install Caskroom/cask/xquartz
brew install r
You can also install R from this page:
https://cran.r-project.org/bin/macosx/
It works out of the box
homebrew/science was deprecated
So, you should use the following command.
brew tap brewsci/science
As per the homebrew page, it is installed with the following command:
brew install --cask r

How to install Allegro 5 on Mac oSX Lion with XCode

I am new to mac development and was wondering how I can install Allegro 5 on my Mac. I want to use allegro with Xcode, and I am running Lion. How do I install allegro?
This can found here: http://wiki.allegro.cc/index.php?title=OSX,_Xcode_4,_Framework
If you are using OS X Lion (10.7.x) and Xcode 4.3 you will run into an issue that is not explained in the wiki. When I would attempt to create a new project and include all the frameworks as instructed and after several hours of truing to find an answer I finally stumbled across my issue.
What you may see is an error similar to:
Undefined symbols for architecture x86_64:
"_main", referenced from: ......
This is because for whatever reason AllegroMain-5.0.framework was not added to Summary->Linked Frameworks and Libraries. once you add this its should work!
Install homebrew in Link
Use the Brew by following these steps:
brew install cmake
brew install zlib
brew install freetype
brew install jpeg
brew install libogg
brew install physfs
brew install libpng
brew install flac
brew install ffmpeg
brew install allegro5
Works for me
