Installing ROOTR


I am trying to install and use ROOTR following the instruction posted here: … Guide.html, but when I run the last instruction I get an error:

$  make -j n
make: *** No rule to make target `n'.  Stop.

Some extra information that may be useful:

Mac OS Sierra 10.12
Xcode Version 8.0 (8A218a)
Root version: 6.06/08, Built for macosx64 From heads/v6-06-00-patches@v6-06-06-30-g3bae07b
R version 3.3.1 (2016-06-21)
cmake version 3.6.2
xquartz version 2.7.9

Also, the video linked in the page ( is private.

Thank you very much in advance!

Replace n with the number of cores in your system

Or just:

I have updated the R guide.
