Hi,
To pretty print aggregates by various dimensions I needed to add a
empty row in output of aggregate.
For example.
d<-(aggregate(data[,cbind("x")], by=list(data$group1,data$group2),
sum))
Group.1 Group.2 x
1 A N 3
2 A Y 2
3 B N 420164905
Is there a way to add an empty row between group1 and group 2.
So that it looks like
Group.1 Group.2 x
1 A N 3
2 A Y 2
3
4 B N 420164905
I need to format a series of aggregates by multi dimensions and I wanted
to break the data by empty row between group 1 that people can see some
space.
Also is there a way to add subtotals by group 1 into the mix :
Group.1 Group.2 x
1 A N 3
2 A Y 2
3 5
4 B N 420164905
5 420164905
original data is something like:
data
Group1 Group2 x
A Y 1
B N 1
A Y 1
B N 420164904
A N 3
thanks
Dhruv
