如何在电子邮件正文中嵌入交互式图表

Question

我正在测试dygraphs，我想要的是生成一个html文件，然后通过电子邮件发送它，以便outlook可以打开它，我看到正文中的内容（不只是附件）

这是this post

的扩展

这是dygraphs.Rmd

---
output:
  html_document:
    fig_width: 6
    fig_height: 4
    self_contained: no
---

```{r}
require(dygraphs)
dygraph(nhtemp, main = "New Haven Temperatures", ylab = "Temp (F)") 
```

以下代码可以使用并发送电子邮件（dygraphs.r）

library(dygraphs)
library(mailR)
library(rmarkdown)

send <- function(subject, body){
  send.mail(from = "me",
            to = "me",
            subject = subject,
            html = T,
            inline = T,
            body = body,
            smtp = list(host.name = "smtp.gmail.com", port = 465, user.name = "me", passwd = "pwd", ssl = T),
            authenticate = T,
            send = T)
}

knitr::knit2html(input='dygraphs.Rmd', output='dygraphs_knitr.html',options = "")
rmarkdown::render('dygraphs.Rmd','html_document','dygraphs_rmarkdown.html')
send('dygraphs_knitr', 'dygraphs_knitr.html')
send('dygraphs_rmarkdown', 'dygraphs_rmarkdown.html')

我这样做，我收到了电子邮件，但图表没有呈现。 是否有解决方法（如果可能的话）？
