R package geoR won't install on macOS despite available tcl-tk on the system

Question

I've installed R and RStudio via brew. For a project I need a function from the R library geoR which in turn is dependent on tcl-tk. I installed this as well via brew: brew install tcl-tk. However, trying to install geoR still leads to the error below - which I don't get. Reinstalling R/RStudio didn't help. Nor did re-starting my Mac. Oh, and trying to install geoR from the downloaded binary from CRAN doesn't help either...And lastly, trying to install the tcl-tk package from the R website doesn't solve this either.

I also posted this on the GitHub of brew - but perhaps others visit the realms of StackOverflow.

Answer 1

Well, after a lot of googling, and analyses of what I read, I deduced a solution.

Here I add some background on why I needed a solution and the Step-by-Step procedure I took. Note it certainly is not a final solution/procedure and maybe some steps are redundant - I'll let that to others.

Background

Sometimes data is very skewed and contains a lot of 'zeros' (or very small numbers approaching 'zero'). Before analyses such data need normalisation to meet the assumptions of a statistical test (you can find more on transformation and normalisation here). Usually people log-transform (e.g. natural log, or log₂), the disadvantage is that you loose the 'zeros'.

In my case that is an issue, because the measurements made were properly done (no technical issues), so 'zero' really represents 'zero'. In other words: I don't want to loose them. Some years back a colleague of mine pointed me to 'Box-Cox' transformation (you can find more on that here), and this method is available in R via the geoR package.

The thing is: I use brew to install R and many other packages/libraries lacking on macOS, e.g. wget. For reasons I still don't get - but I also realize it's beyond my coding capabilities - brew does not normally install R with the tcl-tk package. And let that be the critical part you need for geoR and by extension the function boxccoxfit to work. After some googling I got some hints that led me to a (on the face of it) permanent solution; the discussion on the brew website were critical.

Step-by-Step

1. I made sure I have tcl-tk installed via brew.

   • brew install tcl-tk
   • I made sure tcl-tk was in my path: echo 'export PATH="/usr/local/opt/tcl-tk/bin:$PATH"' >> ~/.bash_profile.
   • The command wish also confirmed this.

2. I also made sure I had installed Command Line Tools properly - there were some updates to High Sierra in the last week, and others had reported issues with that, so I feared it might had to re-installed. I didn't have to, but here's how I checked that. The command brew config shows:

   X11: 2.7.11 => /opt/X11
   

   The bold printed line suggests that Command Line Tools should be installed.
   
   

3. I than double checked if the path was really set, using the command xcode-select -p, which shows:

   /Library/Developer/CommandLineTools

   
   

4. Also gcc is properly set. I checked this using gcc --version, which shows:

   Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
   Apple LLVM version 9.0.0 (clang-900.0.39.2)
   Target: x86_64-apple-darwin17.4.0
   Thread model: posix
   InstalledDir: /Library/Developer/CommandLineTools/usr/bin

   
   

5. Now that I had confirmed the basics are present, I proceeded by re-installing Xquartz, R and RStudio. To make sure I get the R with tcl-tk I used the R version of @srfore. These are the subsequent commands.

   • brew cask reinstall xquartz, re-install Xquartz. Optional, if already installed.
   • brew reinstall -s sethrfore/homebrew-r-srf/r, installed a edited version of R.
   • brew cask reinstall rstudio, re-install Rstudio. Optional, if already installed.

6. All seemed well, I double checked with brew doctor.

   Your system is ready to brew.

7. Of course, for me, this all started with the need to use the function boxcoxfit from the R package geoR which is dependent on tcl-tk. So, now it was showtime and I started R:

   install.packages("geoR")
   Installing package into ‘/usr/local/lib/R/3.4/site-library’
   (as ‘lib’ is unspecified)

   To many to show here, so I deleted this part.
