Hello together,

I have a data.frame, which I would like to export to excel.
This works without problems. My problem is, that i can't sum one of the
colums.

If i try this, i get the sum of this column.
> sum_PT_PROG<-sum(data_export_final_sort$PT_PROG,na.rm=TRUE)
> sum_PT_PROG
[1] 130

But how can i get this result under my column for the Excel Export?
Now my Excel Export looks like this one.
PT_PROG
23
100
7

and now i want under this digets the sum of this column (130)?

Thanks for your help.

Mat
