R中的Snowball和SnowballC包是不同的？

Question

我stemDocument用于使用tmR中的包来阻止文本文档.示例代码:

data("crude")
crude[[1]]
stemDocument(crude[[1]])

我收到一条错误消息:

loadNamespace(name)出错:没有名为'Snowball'的包

我已经安装了SnowballC包,无法找到Snowball包.以下是我的sessionInfo():

R version 2.15.3 (2013-03-01)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

locale:

attached base packages:

other attached packages:
[1] SnowballC_0.5 tm_0.5-8.3   

loaded via a namespace (and not attached):
[1] slam_0.1-31  tools_2.15.3

它需要任何其他包裹还是雪球？

Answer 1

只是尝试将SnowballC软件包安装到R

install.packages("SnowballC")

library(SnowballC)

它应该工作.

Answer 2

你有一个旧版本pkg:tm.当前版本tm有一个描述SnowballC为"建议" 的描述文件.旧版本建议使用Snowball.

Package: tm

这是您目前从CRAN获得的消息:

Package ‘Snowball’ was removed from the CRAN repository.

Formerly available versions can be obtained from the archive.

您应该更新到当前版本tm.试试这个:

update.packages("tm",  checkBuilt = TRUE)
