[R] aggregate empty row for pretty appearance also subtotal if possible

[jim holtman]

You can also use the 'reshape' package:

> d.m <- melt(dat, measure.var='x')
> d.m
  Group1 Group2 variable     value
1      A      Y        x         1
2      B      N        x         1
3      A      Y        x         1
4      B      N        x 420164904
5      A      N        x         3

> cast(d.m, Group1+Group2~., sum, margins=TRUE)
  Group1 Group2     (all)
1      A      N         3
2      A      Y         2
3      A  (all)         5
4      B      N 420164905
5      B  (all) 420164905
6  (all)  (all) 420164910
