我有很多 (1400) 封 outlook 电子邮件(.msg 格式)需要进一步处理。 R 满足我的大部分文本挖掘需求，但为此我找不到任何解决方案。 我使用了来自 tm.plugin.mail 的 readMail，但没有成功
newsgroup <- file.path("D:", "mails")
news <- VCorpus(DirSource(newsgroup), readerControl = list(reader = readMail))
inspect(news)
任何帮助/建议将不胜感激
谢谢!...
最佳答案
您现在可以使用 msgxtractr这样做:
devtools::install_github("hrbrmstr/msgxtractr")
library(msgxtractr)
print(str(read_msg(system.file("extdata/unicode.msg", package="msgxtractr"))))
