Optionally upload a CSV of data that will be available as data frame "df":

(x <- c(sort(sample(1:20, 9)), NA)) (y <- c(sort(sample(3:23, 9)), NA)) union(x, y) intersect(x, y) setdiff(x, y) setdiff(y, x) setequal(x, y) ## True for all possible x & y : setequal(union(x, y), c(setdiff(x, y), intersect(x, y), setdiff(y, x))) is.element(x, y) # length 10 is.element(y, x) # length 8 df = data.frame(x, y) df df[df$x > 9,]
