[R] RQDA/RGtk2 Installation Problem

[Ryoko Yamamoto]

Greetings,

I have been having a problem installing RQDA on my Mac (OS 10.13.2). I
followed the installation process on the RQDA page (
http://rqda.r-forge.r-project.org/), but I keep getting an error message
saying that I am missing pkg-config and GTK. I reinstalled XQuartz and GTK+
2.24.17 multiple times (and reinstalled R version 3.4.4), but kept
receiving the same error message. I also tried to install RGtk2 from
MacPort, but got the same error messages. I am posting the log below, in
hope it will help someone to see the problem/solution.

In my Googling for solution, I saw some other people posting the same
problem, but have not seen a solution. I'd appreciate if anyone could help
me to fix this. I really would love to be able to use RQDA!

Thanks in advance for your help.

Ryoko
