[R] data.frame question

hello can you show me how to create a data.frame from two factors x and y. column 1 should be equal to x and column 2 is 1 if it is common to y and 0 if it is not. x=factor(c("A","B","C","D","E","F","G")) y=factor(c("B","C","G")) the output should look like this: A0 B1 C1 D0 E
