John, You could spin your wheels for a long time on this, because it seems that you lack some basic information, not related to R. You best plan might be to drop consideration of R for a few weeks, to brush up on the basics. But, if just need to get R working for some particular one-off task, your should consider finding someone local you can help you in-person, in exchange for a coffee / beer / lunch.

If it would be about errors installing R, that would be different. I think using MacPorts might actually be the "error" that needs correction. I would suggest an alternate strategy. Go to http://r.research.att.com/libs/ and get the appropriate version of cairo, probably the most recent one. http://r.research.att.com/libs/cairo-1.14.2-darwin.13-x86_64.tar.gz Scroll down to the bottom of that page and an appropriate modification of the two lines for unpacking to the root. curl -O http://r.research.att.com/libs/cairo-1.14.2-darwin.13-x86_64.tar.gz sudo tar fvxz gmp-4.2.4-darwin8-bin4.tar.gz -C / The Mac version of R does not do well with either MacPorts or homebrew installation of required system packages because those package managers put them in loaction that are not recognized by the static build that is the default. Using homebrew (and as far as I know Macports as well) works without major problems. The problem start when you mix standard installations / homebrew / Macports. This results in problems. The fact that the original poster had obviously not used MacPorts (and perhaps did not even know what it was) suggests that the appropriate reply should be to discourage him from using it and offer a strategy with greater likelihood of success in combination with the more typical installation method for the Mac R fork. So: each of the approaches has it’s own pros and cons - it is only that homebrew and Macports are not officially supported by the R team. One of the cons is that both homebrew and MacPorts requires a greater knowledge of the Unix under-pinnings of MacOS. If a poster is asking how to install MacPorts, it suggests that he don't already have such skills and perhaps doesn't even have the motivation to acquire them. (Your earlier response suggested that posting in R-SIG-Mac was the wrong way to do acquire such skills and I agree. Appears the poster has not yet developed the habit of reading supporting online documentation. He certainly did not do so regarding R-SIG-Mac. My opinion: A person who chooses not to read or heed online documentation should be actively discouraged from using either MacPorts of homebrew.) Best; David. Cheers, Rainer -- David.

I tried to install Macports on my Mac OS Sierra 10.12.6, and type "sudo port install cairo", but it did not respond. I haven't seen any file name or app called Macports, but one file called "port" which is located at loca/bin/port" How should I do it?
