Reduce may be handy here:
ans = Reduce(function(a,b)merge(a,b,by=1),yoda)
names(ans)[2:ncol(ans)] = names(yoda)

This will do it:
> merge(A, B, by = 1, all = TRUE)
Date Value.x Value.y
1 03/15/10 1 5
2 04/15/10 2 5
3 05/15/10 3 NA
4 06/15/10 NA 5
but you probably really want to be using time series for this so that
you can easily perform other operations t
Hello,
I have for a long list of data.frames that I would like to get merged.
Each data.frame have two columns with the same names (Date and Value).
What I would like is for the objects in the list to be merged on Only
date with the column header being the name in the list.
For example
A <- data
3 matches
