失败并发生错误：R 3.0.0之前已构建“包'sentiment'：请重新安装”

Question

我正在尝试运行snaMIC.R脚本，该脚本正在对Twitter数据进行情感分析。 但是它失败并显示一条错误消息，指出软件包情感是在R 3.0.0之前构建的：请重新安装。 我正在使用R-3.1.0 i386（32位胜利）。 我注意到的另一件事是，我没有在“安装软件包”下获得情感软件包。 我从http://cms.unipune.ernet.in/~webmaster/cran/bin/windows/contrib/2.14/sentiment_0.2.zip下载了sentiment_0.2.zip文件，并在默认的R Win库下成功将其解压缩。 但是，情感包在“安装包”下仍然不可用。 我添加了更多存储库，但这无济于事。 任何建议将不胜感激。

Answer 1

首先，我注意到URL实际上提供了下载RStem.zip的功能，而不是sendiment_0.2.zip。

我认为您的错误消息更有用的说法是：您已经下载了R 2.14的二进制软件包，然后找到R 3.0（或更高版本）的二进制软件包，然后下载并安装它。

这是3.1程序包： http : //www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.1/

因此，也许您可​​以尝试下载并安装： http : //www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.1/Rstem_0.4-1.zip

如果那不起作用，您可以尝试查找源软件包并以这种方式安装。 但是在Windows上可能并不简单...

Answer 2

我已经解决了以上问题的解决方案：“失败，错误：'R'3.0.0之前已构建'package'sentiment'：请重新安装它”。 从R控制台使用了以下命令序列：

require(devtools)
install_url("http://cran.r-project.org/src/contrib/Archive/sentiment/sentiment_0.2.tar.gz")
require(sentiment)
ls("package:sentiment")
