Did you upgrade cpp in homebrew after the installation from R? Errors
like seem to happen when compiler versions / libraries don't match.

If yes, reinstall libjpeg and the cairo programs, and, maybe, even R.

Otherwise I would suggest to try the same in an R session from the
terminal and see if you have the error there - because I don't know how
well RStutio works together with homebrew installed R - doesn't RStudio
come with  it's own R installation?

Cheers,

Rainer
