Hello,

Try the following. (I don't remember who wrote this function but I saw it in R-Help)



setdiffDF <- function(A, B){
    f <- function(A, B)
        A[!duplicated(rbind(B, A))[nrow(B) + 1:nrow(A)], ]
    df1 <- f(A, B)
    df2 <- f(B, A)
    rbind(df1, df2)
}

df1 <- data.frame(A = 1:10, B = 11:20)
df2 <- data.frame(A = 1:5, B = 11:15)
setdiffDF(df1, df2)


Hope this helps,

Rui Barradas

Hi,

I have two data frames, say, x and y, where y is a subset of x. How
can I find the set difference of these two data frames (i.e., x-y)?

Thanks,
