使用mailR通过R发送邮件

如何解决使用mailR通过R发送邮件

不确定为什么这对我不起作用。当然，我没有设置其他任何东西。在运行此程序之前，我需要在gmail中进行任何设置吗？

library(mailR)

send.mail(from="[e-mail]",to="[e-mail]",subject="Test Email",body="PFA the desired document",html=T,smtp=list(host.name = "smtp.gmail.com",port = 465,user.name = "[e-mail]",passwd = "xxxxxxx",ssl = T),authenticate=T)

这是我得到的错误：

即使说我的用户名和密码不正确，我还是检查并输入了
