Hello,

(Sorry if this is a dup post...)

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 = 'ccqu...@gmail.com'",
 "toaddrs  = 'userna...@somethinghere.com'"
- Show quoted text -
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
