Data Manipulations and SQL
...data frames and
both of them have a column called "id", then I want to join this two
data frames into one. In SQL, we can just simply use the join comment.
What should we do in R? Is there any package that allows us to run SQL
statements with R data?
Thank you in advance for your help,
Willa
