我一直在尝试用gmail地址从r发送电子邮件,但我总是得到相同的错误代码。有没有办法纠正这个错误。我知道以前也有人问过类似的问题,但用这些答案我想不出来。谢谢你的帮助
而且,我的google账户的参数已经调整过了。
以下是我发送电子邮件的代码:

library(mailR)
sender <- "abc@gmail.com"
recipients <- c("abc@gmail.com")
send.mail(from = sender,
          to = recipients,
          subject = "Subject of the email",
          body = "Body of the email",
          smtp = list(host.name = "smtp.gmail.com", port = 465, 
                      user.name = "abc@gmail.com",            
                      passwd = "123abc", ssl = TRUE),
          authenticate = TRUE,
          send = TRUE)

这是错误代码

自Java9发布以来 javax.activation 已删除。因此,如果您需要使用Java9或更高版本,只需安装这些JAR
https://mvnrepository.com/artifact/javax.activation/javax.activation-api/1.2.0
https://mvnrepository.com/artifact/com.sun.activation/javax.activation/1.2.0 并投入 system.file("java", package = "mailR") 文件夹。
