I recently upgraded my mac to Sierra (previously I was using Mountain Lion) and I also updated R to run 3.3.2 (from 3.1.2). Now, whenever I attempt to open a file in R I will get the spinning pinwheel and then I have to force quit `R.
It doesn't happen all the time (about 7 times out of 10) and I'm not certain why. Typically I am using something like:
read.csv(file.choose())
read.dat(file.choose())
Even if I set my working directory to the folder where the data set is, I still end up getting the problem.
Any ideas on what might be going on here?
