R help - Jun 2005 - "\n" in legend using substitute and as.expression

Dear R users,
Is it possible to force a hard return in an expression. I tried including 
one for a legend using an expression and it didn't work. Here is my code,
legend(12, 0.10, c("Fitted density",
    as.expression(substitute(paste("Weibull (", alpha==shapeU," ,
",
beta==scaleU,") Mean = ",meanU," days"),
list(shapeU = round(mle.r$estimate[1],3),
         scaleU = round(mle.r$estimate[2],3),
         meanU = round(mle.r$estimate[3),4)))) ),
    lty=c(1,1),col=c(1,2),lwd=c(1,1),merge = TRUE)

Thanks,
Vumani

Please try to specify *reproducible* examples. For the above example, we 
do not have the plot and the data. Additionally, the stuff above is not 
even syntactically correct as e.g. in:
     meanU = round(mle.r$estimate[3),4)))) ),
                                 ^ ^
It has been described in former messages on this list (hence in the 
mailing list archives) that newlines are not really supported in the 
"mathematical annotation environment".
