...particular not using *methods*will reduce the start-up time by a factor of up to two. But it can also be used to customize R, e.g. for class use. Rscript also checks the environment variable R_SCRIPT_DEFAULT_PACKAGES; if set, this takes precedence over R_DEFAULT_PACKAGES.

Someone said it used a possibly platform-dependent higher-than-double-precision type.
