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".
