Suppose I have two similar data.frames
x1 <- data.frame(letters[1:26],1:26,1:26)
x2 <- data.frame(letters[1:26],1:26,1:26)
How would I create a new data frame that adds the 2nd column of each data frame together and the 3rd column of each data frame together.
Such that x3[2] = c(2,4,6,8,…) ?
Did you have this in mind?
