Hi, I have 2 tables, for example table a:
var_a var_b 1 a 2 b
table b:
var_a var_b 3 c 4 d
They have the same variable names for both of the tables but different value. I want to merge those 2 table into table c which is:
var_a var_b 1 a 2 b3 c4 d
I think it's quite easy problem but didn't found the simple way to do it. Thank you!
