我正在使用R 中的包stemDocument来提取文本文档tm。示例代码:

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

我收到一条错误消息:

loadNamespace(name) 中的错误:没有名为“Snowball”的包</p>

我已经安装了SnowballC包,但找不到 Snowball 包。下面是我的sessionInfo()

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

locale:
[1] en_CA.UTF-8/en_CA.UTF-8/en_CA.UTF-8/C/en_CA.UTF-8/en_CA.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

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

它是否需要任何其他软件包或 Snowball?

只需尝试将SnowballC软件包安装到 R

install.packages("SnowballC")

library(SnowballC)

它应该工作。

您有旧版本的pkg:tm. 当前版本tm有一个说明文件,SnowballC列为“建议”。旧版本建议使用 Snowball。

Package: tm
Title: Text Mining Package
Version: 0.5-10

Authors@R: c(person("Ingo", "Feinerer", role = c("aut", "cre"),

             person("Kurt", "Hornik", role = "aut"),
             person("Artifex Software, Inc.", role = c("ctb", "cph"),

Depends: R (>= 2.14.0)

这是您目前从 CRAN 收到的消息:

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的tm. 尝试这个:

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