mailR:如何在电子邮件中将rmarkdown文件作为正文发送？

Question

如何rmarkdown使用R在电子邮件中将生成的文档作为正文发送？

我已成功尝试knitr过mailR,但是当使用(新)rmarkdown-package 生成html-report时,它失败了.

library(mailR)
send.mail(
  from = "FROM@gmail.com",
  to = "TO@gmail.com",
  subject = "MyMail",
  html = T,
  inline = T,
  body = "my_report.html",
  smtp = list(host.name = "smtp.gmail.com", port = 465,
    user.name = "USERNAME", passed = "PASSWORD", ssl = T),
  authenticate = T,
  send = T
)

错误:

org.apache.commons.mail.EmailException: Building the MimeMessage failed

我想这与以下行做:广东话解决以下文件资源:/用户/用户名/ MyFolder中/./数据:图像/ PNG;的base64？

我对任何指导都非常感激.

mailR当前不支持解析使用数据URI方案(http://en.wikipedia.org/wiki/Data_URI_scheme)编码的内嵌图像.

目前,我建议使用以下解决方案来解决您的问题.在将来,我将考虑让mailr本地支持这个.

首先,从R终端创建HTML文件(这里重要的是选项不包括" base64_images"---见?markdown::markdownHTMLOptions):

library(knitr)
knit2html("my_report.Rmd",options="")

现在您可以通过mailR发送生成的HTML文件:

send.mail(from = "FROM@gmail.com",
          to = "TO@gmail.com",
          subject = "MyMail",
          html = T,
          inline = T,
          body = "my_report.html",
          smtp = list(host.name = "smtp.gmail.com", port = 465, user.name = "USERNAME", passwd = "PASSWORD", ssl = T),
          authenticate = T,
          send = T)
