Problems installing shiny

Hello, I am trying to install shiny and having issues with its dependencies. My server is an Ubuntu 14.04 using nginx as the web server. When I run the statement sudo su - -c “R -e "install.packages(‘shiny’, repos=‘http://cran.rstudio.com/’)"” at the command line, it starts to work. Here is the info that is returned when attempting to install.

• installing source package ‘Rcpp’ … ** package ‘Rcpp’ successfully unpacked and MD5 sums checked ** libs g++ -I/usr/share/R/include -DNDEBUG -I…/inst/include/ -fpic -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -g -c Date.cpp -o Date.o g++ -I/usr/share/R/include -DNDEBUG -I…/inst/include/ -fpic -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -g -c Module.cpp -o Module.o g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, with preprocessed source if appropriate.

• removing ‘/usr/local/lib/R/site-library/shiny’

The downloaded source packages are in ‘/tmp/RtmpduxxBi/downloaded_packages’ Warning messages: 1: In install.packages(“shiny”, repos = “https://cran.rstudio.com/”) : installation of package ‘Rcpp’ had non-zero exit status 2: In install.packages(“shiny”, repos = “https://cran.rstudio.com/”) : installation of package ‘httpuv’ had non-zero exit status 3: In install.packages(“shiny”, repos = “https://cran.rstudio.com/”) : installation of package ‘shiny’ had non-zero exit status

So it appears two of the dependencies (Rcpp and httpuv), so far, while unpacking are not installing.

Does anyone know what may be causing this and even better, how to fix this issue? Thank you in advance for any solutions!
