6 3:YMZ7.EC 12/03/2007 08:30:00 EC A 83916534 13388 1
I wanted the average of the B's and A's. I wrote this to perform that.
NPrice <-
(YM1207$Price[which(YM1207$TickType=="B")]+YM1207$Price[which(YM1207$TickType=="A")])/2
head(NPrice)
[1] 13387.5 13387.5 13387.0 13386.5 13386.5 13387.0
Now since NPrice is much smaller than the original dataframe, YM1207 I can
not just add NPrice to the set.
How can I put each of tho...
