How to email an R markdown report in any format (PDF, HTML, WORD) when it is generated?

I have an R shiny application that generates an R markdown report in any format depending on what the user clicks. I want to email this report to myself every time it is generated I seem to not find much about this online. I wondering if anyone has any idea how to start this

Solution

You could try the mailR package. From the mailR github documentation, you can send an email and use attach.files to attach the relevant report.

library(mailR)
send.mail(from = "[email protected]",
          to = c("[email protected]", "[email protected]"),
          subject = "Subject of the email",
          body = "Body of the email",
          smtp = list(host.name = "smtp.gmail.com", port = 465, ssl = TRUE,
                      user.name = "gmail_username", passwd = "password"),
          authenticate = TRUE,
          send = TRUE,
          attach.files = c("./download.log"),
          file.names = c("Download log.log"),
          file.descriptions = c("Description for download log"))

sendmailR can achieve a similar result but the attachment is added to the body of the email using mime_part().

library(sendmailR)
from <- '[email protected]'
to   <- '[email protected]'
subject <- 'Email Subject'
body <- list('Email body text.',
             mime_part(x = 'pathToAttachment', y = 'nameOfAttachment'))
sendmail(from, to, subject, msg = body,
         control = list(smtpServer='ASPMX.L.GOOGLE.COM'))
