Hello,
I need to clarify, Henrique's suggestion worked great for getting the text
that I needed via cat(), but I haven't sorted out how to get cat() like
output into a variable so I can pass it into the message body variable I am
using.
Here is what I mean:
x
[1] "a" "b" "c" "d"
paste(x,collapse='\n')
[1] "a\nb\nc\nd"
y = paste(x,collapse='\n')
cat(y)
a
b
c
d
This is the problem with 'y' has the msg body:
paste("msg = MIMEText('",y,"')",sep="")
[1] "msg = MIMEText('a\nb\nc\nd')"
This is what I am after (I think!):
paste("msg = MIMEText('",y,"')",sep="")
[1] "msg = MIMEText('a
b
c
d')"
Here is how I am actually using it (with sensitive items generalized):
require(rJython)
rJython <- rJython()
rJython$exec( "import smtplib" )
rJython$exec("from email.MIMEText import MIMEText")
rJython$exec("import email.utils")
mail<-c(
#Email settings
"fromaddr = '[email protected]'",
"toaddrs = '[email protected]'",
#"msg = MIMEText('test message from R')",
paste("msg = MIMEText('",y,"')",sep=""), # my message in this example is
'y'
"msg['From'] = email.utils.formataddr(('gmail acct', fromaddr))",
"msg['To'] = email.utils.formataddr(('cc email!', toaddrs))",
"msg['Subject'] = 'test with y'",
#SMTP server credentials
"username = '[email protected]'",
"password = 'a password here'",
#Set SMTP server and send email, e.g., google mail SMTP server
"server = smtplib.SMTP('smtp.gmail.com:587')",
"server.ehlo()",
"server.starttls()",
"server.ehlo()",
"server.login(username,password)",
"server.sendmail(fromaddr, toaddrs, msg.as_string())",
"server.quit()")
jython.exec(rJython,mail) # and here is the error I get.
Error in ls(envir = envir, all.names = private) :
invalid 'envir' argument
Just in case someone asks, I can do this:
y = "a test"
...and the above email sends fine with 'a test' as the msg body.
Any ideas?
PS - I received lots of suggestions. Thank you very much for your
effort/input.
Ben
