使用Merge合并R中的列表数据？

Question

I would like to combine two lists:

data1 data2
a 1     a 1
b 2     b 2
c 3     c 3
d 4     f 6
e 5     g 7

so that the final product is:

data3
a 1
b 2
c 3
d 4
e 5
f 6
g 7

I have tried using variations of merge, but inevitably end up loosing something from each list.

Thank you for your help! Thank you!

Answer 1

使用参数all=TRUE的merge ：

merge(data1,data2,all=TRUE)

Answer 2

要考虑的一种选择是

unique(rbind(data1, data2 ) )
