In the benchmarks docs, https://github.com/nodejs/node/blob/master/benchmark/README.md, the instructions say to install 2 R packages,

install.packages("ggplot2") install.packages("plyr")

but running those commands in the R repl returns a --- Please select a CRAN mirror for use in this session ---

should be somehting like this, install.packages("ggplot2", repos="http://cran.us.r-project.org")

Sure, we can specify the mirror, but not everybody lives in the US. I don't think entering a number and pressing enter in the REPL is a big issue. This is what my REPL shows:

interesting thing, i don't get that list, but i do get a XQuartz installer pop up, i'll probably add these scenarios to the PR

[Fishrock123]

Yeah, on OS X for me X11 pops up and I didn't see that at the time because I was using two monitors.

[AndreasMadsen]

@lholmquist @Fishrock123 I see, I properly have a custom install of R.

[AndreasMadsen]

options(menu.graphics = FALSE) will apparently disable X11. But I'm also fine with specifying the repo or documenting X11. I guess specifying the repo is the most foolproof.
