I'm working with Rserve via Ruby bindings. It's pretty trivial to establish a connection to Rserve, and I assume its a good idea to persist that connection globally to avoid the overhead of tearing it down and re-building it as needed (I'm not operating in a multi-threaded environment).
我正在通过Ruby绑定使用rservice。建立rservice的连接是非常简单的，我认为在全局上持久化这个连接是一个好主意，以避免在需要的时候破坏它并重新构建它(我不是在多线程环境中操作)。
Since the objects defined will stick around, and potentially class with later operations, I want to clear them out. I've seen:
因为定义的对象将会继续存在，并且有可能在以后的操作中使用类，所以我想把它们清除掉。我看过:
myvar = 1
rm(myvar)
However, I would rather re-initialize everything, to avoid having to manually keep track of whats defined. Is this possible? Is there a significant overhead associated with it if so?
但是，我宁愿重新初始化所有东西，以避免手工跟踪定义的whats。这是可能的吗?如果有的话，是否存在与之相关的重大开销?

it is a bit dangerous but: rm(list=ls()) really, don't do this.
这有点危险，但是:rm(list=ls())真的，不要这样做。
