Why weird?
See below:
DF - read.table(text=
Houseid,Personid,Tripid,taz
1,1,1,4
1,1,2,7
2,1,1,96
2,1,2,4
2,1,3,2
2,2,1,58
Thanks a ton!
It was weird because according to me ordering should have by default.
Anyways, your workaround along with Weidong's method are both good
solutions.

I have a dataframe imported from csv file below:
Houseid,Personid,Tripid,taz
1,1,1,4
1,1,2,7
2,1,1,96
2,1,2,4
2,1,3,2
2,2,1,58
There are three groups identified based on the combination of first and
second columns. How do I split this data frame?
I tried
aa - split(inpfil, inpfil[,1:2])
but it
how about
split(inpfil, paste(inpfil[,1],inpfil[,2],sep=','))
