Sending/Receiving Emails

1. There are many ways to send email in R. First, you can use sendmail{sendmailR}. The following code is a simple test email.

   sendmail(from="firedragon.du@gmail.com",
   to="dclong@iastate.edu",
   subject="Sending Email from R",msg="It works",
   control=list(smtpServer="mailhub.iastate.edu"))
   

   In this way, you can attach objects in R directly to the email, but it does not support email authentication, and it does not support multiple recipients very well. Second, you can call code written in other languages in R to send emails. For example, you can use rJava to call Java code to send emails in R. I have written an R package dclong.jmail based on Java Mail API which can be used to send/receive emails. It supports email authentication. Another way is to use system or shell to call executable applications to send emails. There are many such email applications in Linux system. For Windows system, the application sendEmail written by Brandon zehm is good one, which support Gmail, multiple recipients and multiple attachments.
