In a situation where you need to merge two datasets in R using dplyr, but the key columns have different names, how would you approach this?
- bind_rows()
- left_join()
- merge() with by parameter
- rename()
To merge datasets in dplyr with different key column names, you can use the rename() function to rename the key columns in one or both datasets, ensuring they match. This allows you to then use the standard left_join() or other merge functions.
