Just wanted to start a discussion on whether R could ship with more
appropriate GC parameters. Right now, loading the recommended package
Matrix leads to:
> library(Matrix)
> gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 1076796 57.6 1368491 73.1 1198505 64.1
Vcells 1671329 12.8 2685683 20.5 1932418 14.8
Results may vary, but here R needed 64MB of N cells and 15MB
