R: Can't install certain packages

Question

I noticed that I am unable to install a bunch of packages. It started then I was trying to install the package carat . I would get this long error.

ERROR: compilation failed for package ‘robustbase’
* removing ‘/Users/regiswengel/anaconda/lib/R/library/robustbase’
Warning in install.packages :
  installation of package ‘robustbase’ had non-zero exit status
ERROR: dependency ‘robustbase’ is not available for package ‘ddalpha’
* removing ‘/Users/regiswengel/anaconda/lib/R/library/ddalpha’
Warning in install.packages :
  installation of package ‘ddalpha’ had non-zero exit status
ERROR: dependency ‘ddalpha’ is not available for package ‘recipes’
* removing ‘/Users/regiswengel/anaconda/lib/R/library/recipes’
Warning in install.packages :

ERROR: dependency ‘recipes’ is not available for package ‘caret’

Warning in install.packages :

installing the dependencies 'robustbase', 'ddalpha', 'recipes' individually beforehand doesn't work either.

I also noticed that I am unable to update the packages

• cluster
• glmnet
• maps
• PKI
• a bunch of others

I'm currently using R version 3.3.2 and RStudio Version 1.0.136 . I have been using R and RStudio for months and have never had an issues installing packages. I have done a bunch of searching on Google and Stack-overflow and found some solutions. None of them have worked for me.

Answer 1

The error in my output was

gfortran -fPIC -I/Users/UserName/anaconda/include -L/Users/UserName/anaconda/lib -c eigen.f -o eigen.o

make: gfortran: No such file or directory

I found this thread that provided me with the answer I needed.

OS X package installation depends on gfortran-4.8
