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?
