R Studio

Consider the tables below

bands:

name	lastname	band	year
Mick	Jagger	Stones	1962
John	Lennon	Beatles	1960
Paul	McCartney	Beatles	1960
Paul	McCartney	Wings	1971

instruments:

artist	artistname	plays	model
John	Lennon	guitar	Gibson
Paul	McCartney	bass	Hofner
Keith	Richards	guitar	Fender
Paul	McCartney	bass	Hofner

Draw the output table from the following operations (you should be able to calculate the output by hand though you may use R to check your answers).

1. bands %>% inner_join(instruments, by=c(name="artist", lastname="artistname", year="plays"))
