R help - Jun 2013 - addtable2plot problem with adding summary object

Hello,
I am trying to add a summary generated by summary () to a plot.The output of the
summary is an object of class (summaryDefault,table)
When I try to add it with addtable2plot (x="topright",sum_1)
I get an error:Error in dim(table) : 'table' is missing
Here is some info about sum_1:> print (sum_1)   Min. 1st Qu.  Median    Mean
3rd Qu.    Max.    NA's    0.00   16.43   46.71   87.35  121.70  523.90     
37 > is.table(sum_1)> class (sum_1)[1] "summaryDefault"
"table"
Thank you.
