问题描述
下面的代码行返回以下错误:
The lines of code below return the following error:
">"找不到对象 'readNewsgroup'
">"object 'readNewsgroup' not found
library(tm)
setwd("C:/Users/DanRoDuq/Downloads/20news-bydate-train")
sci.electr.train=Corpus(DirSource("sci.electronics")
,readerControl=list(reader=readNewsgroup,language="en_US"))
我从以下位置获取数据:http://qwone.com/~jason/20Newsgroups/lexData.text，并下载名为 20news-bydate.tar.gz 的文件
I got the data from: http://qwone.com/~jason/20Newsgroups/lexData.text, and downloaded the file called 20news-bydate.tar.gz
当我用 readPlain 替换 readNewsgroup 时，代码会运行，但我遵循的说明告诉我使用 readNewsGroup 设置.我应该加载另一个库吗?
When I replace readNewsgroup by readPlain, the code runs, but the instructions I'm following tell me to use the readNewsGroup setting. Should I maybe be loading another library?
推荐答案
在当前的 tm-Version (0.6) 中不再有名为 readNewsgroup 的阅读器.使用 getReaders()，您可以获得版本的所有可用阅读器.
There is no longer a reader called readNewsgroup in the current tm-Version (0.6).With getReaders() you get all available readers for your Version.
下载与您所遵循的说明相同的版本，并且应该有readNewsgroup 阅读器.
Download the same Version as the instructions you are following and there should be areadNewsgroup reader.
