[R] Data.frame Question

Hi: I want to add a constant to an existing col of the data.frame. I have the following dataset: structure(list(x = c(1, 1, 1, 1, 1), y = c(1, 1, 1, 1, 1)), .Names = c(x, y), row.names = c(NA, 5L), class = data.frame) I want to add a

[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 E0 F0 G1
