The package "websocket" does not install: the compiler is killed due to the infamous 1gb limit. This package is quite new on CRAN. Could it be added to the cache?
g++ -std=gnu++11 -I"/opt/R/3.5.3/lib/R/include" -DNDEBUG -I./lib -I"/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.5/Rcpp/include" -I"/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.5/BH/include" -I"/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.5/AsioHeaders/include" -I/usr/local/include -fpic -g -O2 -c websocket.cpp -o websocket.o g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, with preprocessed source if appropriate.
More generally, it would be nice to have a particular way of requesting packages to be added to the cache, as well as a list of packages which are currently in the cache. I'm not sure whether I am supposed to ask this here!
