multiline system call

system("sh",intern=T,input=c("echo x","echo y"))

Hello,

I am trying to call sendmail from within R via system(). As sendmail reads
from STDIN, I need to pass a multiline input as an argument.

E.g. (not working):

	system('sendmail -f xxx at swing.be -t yyy at swing.be\ntest\n.\n')

I tried a lot of ways to type the EOL characters, but cannot get them work the
right way. This leads to several problems. For instance, R waits for me to
enter <control-D> at the end of the sequence.

Thanks for any help.

Dear Sir,

Le vendredi 22 d?cembre 2006 20:05, vous avez ?crit :

system("sh",intern=T,input=c("echo x","echo y"))

Thanks for the advice, but I do not find doc about the input arg for the
system function. Besides,

$> system("sh",intern=T,input=c("echo x","echo y"))
Erreur dans system("sh", intern = T, input = c("echo x", "echo y")) :
       unused argument(s) (input = c("echo x", "echo y"))

Is R version 2.4.0 (2006-10-03) too old?

Best regards,

Its only available on Windows.

system("echo x\necho y",intern=T)

system("echo x ; echo y",intern=T)

system("echo 'a \n b \n c' | wc ",intern=T)

Perhaps a workaround is to pipe the input into sendmail (I recall sendmail
accepts input from sdtin) from 'echo'

This works fine this way. Thanks a lot.

(but note that my 2.4.0 linux binary does not accept the "input=xyz" as an
argument of the system() function.)
