Selecting rows from a data frame from combinations of lists [duplicate]

Answer 1

We could use dplyr::anti_join() to do the row exclusion filtering for us, if we had two dataframes:

index <- data.frame(col1 = as.character(filter[,1]),
                    col2 = filter[,2])

anti_join(dat, index)

Joining, by = c("col1", "col2")
  col1 col2 col3
1    4    x    d
2    1    y    e
3    2    z    f
4    3    x    g
5    4    y    h
6    1    z    i
7    2    x    j
8    3    y    k
9    4    z    l
