Basically, I want to make a copy of some array b after removing some elements. but not change the original b. I tried splice!(b,1:2) and deleteat!(b,1:2) both would change b. Thanks for any comments!

Julia has no built-in syntax that is equivalent to R’s vector[-indexes]. Try something like a = b[setdiff(1:end,indexes_to_remove)] Of course for these particular elements, b[3:end] will also work.

That helps! Thanks both of you for the reply!
