caught segfault error in R

In case anyone else has this problem or similar in the future, I sent a bug report to the package maintainer and he recommended uninstalling all installed packages and starting over. I took his advice and it worked!

I followed advice from this posting: http://r.789695.n4.nabble.com/Reset-R-s-library-to-base-packages-only-remove-all-installed-contributed-packages-td3596151.html

ip <- installed.packages()
pkgs.to.remove <- ip[!(ip[,"Priority"] %in% c("base", "recommended")), 1]
sapply(pkgs.to.remove, remove.packages)
