A list of data.frames merged together
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.frame(Date=c("03/15/10","04/15/10","05/15/10"),
Value=c(1,2,3))
B <- data.frame(Date=c("03/15/10","04/15/10","06/15/10"),
Value=c(5,5,5))
...
yoda <- list(A=A,B=B,...)
Result:
Date A B C
03/15/10 1 5 ...
04/15/10 2 5
05/15/10 3 NA
06/15/10 NA 5
Any ideas? I have been fiddling around with plyr and reshape without success
Thanks
Dan
