You have no date1 only date. Therefore
result<- merge(data, data3, by=c("date", "name"), all=T)
takes all values from both data frames
> dim(data)
[1] 20 15
> dim(data3)
[1] 20 9
alltogether 24 columns from which 4 are date and name columns therefore 20
columns contain data.
> dim(result)
[1] 40 22
So the result has all 20 columns from both data frames plus one name and
one date column and all rows from both data frames = 40. Those two sets
are disjoint. If you had some common date and name in both data frames
these rows would be merged on the same row in result.
Let us try this.
> data3$name[1:5] <- data$name[1:5]
> data3$date[3:5] <- data$date[3:5]
result<- merge(data, data3, by=c("date", "name"), all=T)
dim(result)
[1] 37 22
