I have two data frame x and y. I am trying two merge this two data frame using sqldf function in R.
Sqldf::sqldf( select * from x join y on x.key=y.key) But this gives me error
Error:can only bind lists of raw vectors (or null)
I tried separately to run and both of them works Sqldf::sqldf( select * from x) or Sqldf::sqldf( select * from y).
