mailR：如何在电子邮件中发送rmarkdown文档？ [英] mailR: how to send rmarkdown documents as body in email?

问题描述

如何发送 rmarkdown 生成的文档作为电子邮件中的一个正文，使用R？

我已经成功尝试 knitr 与 mailR ，但是当与（新）生成html报告时， rmarkdown -package it failed。

  library（mailR）
 send.mail b $ b from =[e-mail]，
 to =[e-mail]，
 subject =MyMail，
 html = T，
 inline = T，
 body =my_report.html，
 smtp = list（host.name =smtp.gmail.com，port = 465，
 user.name =USERNAME ，pass =PASSWORD，ssl = T），
 authenticate = T，
 send = T 
）
  

错误：

  org.apache.commons.mail.EmailException：构建MimeMessage失败

我想这与以下行有关：无法解析以下文件资源：/ Users / USERNAME / myfolder /./ data：image / png; base64 ？

我非常感谢任何形式的指导。

解决方案

mailR目前不支持解析使用数据URI方案编码的内联图像（ http://en.wikipedia.org/wiki/Data_URI_scheme ）。

暂时，我建议以下解决方案来解决您的问题。在未来，我将研究如何使邮件员本地支持。

首先，从R终端创建HTML文件（这里重要的是该选项不包括 base64_images ---请参阅？markdown :: markdownHTMLOptions ）：

 库（knitr）
 knit2html（my_report.Rmd，options =）
  pre> 
 
 
现在您可以通过mailR发送生成的HTML文件：
  send.mail（from =[e-mail]，
 to =[e-mail]，
 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）
  
 
How to send rmarkdown generated documents as a body in an email, using R?

I have successfully tried knitr with mailR, but when instead generating the html-report with the  (new) rmarkdown-package it fails.
library(mailR)
send.mail(
  from = "[e-mail]",
  to = "[e-mail]",
  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
)
error:

I guess it has to do with the following line: Cant resolve the following file resource :/Users/USERNAME/myfolder/./data:image/png;base64?

I'm more than grateful for any kind of guidance.
解决方案
mailR currently does not support resolving inline images encoded using the data URI scheme (http://en.wikipedia.org/wiki/Data_URI_scheme).

For the time being, I suggest the following solution to address your problem. In the future, I will look into getting mailr to support this natively.

First off, create the HTML file from the R terminal (the important thing here is that options does not include "base64_images" --- see ?markdown::markdownHTMLOptions):
library(knitr)
knit2html("my_report.Rmd",options="")
Now you can send the resulting HTML file via mailR:
send.mail(from = "[e-mail]",
          to = "[e-mail]",
          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)
