我创建了一个 PCorpus，据我所知它存储在 HDD 上，代码如下:

I create a PCorpus, which as far as I understand is stored on HDD, with the following code:

pc = PCorpus(vs, readerControl = list(language = "pl"), dbControl = list(dbName = "pcorpus", dbType = "DB1"))

我以后如何重新连接到该数据库?

How may I reconnect to that database later?

推荐答案

据我所知，你不能.数据库"实际上是一个文件哈希对象，您可以按如下方式重新连接和加载，

You can't as far as I'm aware. The 'database' is actually a filehash object, which you can reconnect to and load as follows,

db <- dbInit("pcorpus")
pc<-dbLoad(db)

但它加载每个文件作为它自己的对象.您需要使用 writeCorpus 显式保存到磁盘，并每次调用 PCorpus 重新加载.PCorpus 对象只是提供了一种将 Corpus 对象创建到磁盘而不是内存的方法.

but it loads each file as it's own object. You need to save to disk explicitly using writeCorpus and reload with a call to PCorpus each time. The PCorpus object just provides a way of creating a Corpus object to disk rather than memory.
