Dear all,
how can I remove the row of a dataframe whose selected column matches the value of another dataframe? essentially, is there an equivalent of R’s `%in%`

operator in Julia?
Thanks

Please make an MWE for actual code.

Hi everyone, I want to compare if elements of vector x are in elements of vector y.
In R, I can do this as follows:
> x <- c("a", "b", "c")
> y <- c("b", "a")
> x %in% y
[1] TRUE TRUE FALSE
In Julia, I can do this as follows:
julia> x = ["a", "b", "c"];
julia> y = ["b", "c"];
julia> in.(x, Ref(y))
3-element BitArray{1}:
false
true
true
Now let’s make the vector big:
In R,
> set.seed(123)
> x <- rnorm(100000, 1000, 2)
> y <- rnorm(100000, 1000, 2)
> system.time(x %in% y)
