A full join is a type of data frame operation in R that combines rows from two data frames based on a common key, ensuring that all records from both data frames are included in the final output. If there are matching keys in both data frames, the corresponding values are combined; if a key exists in one data frame but not the other, the missing side will show NA for those columns. This allows for comprehensive integration of datasets while preserving all information.
