[graalvm-users] How to remove/opearte on an R vector through Interop?

I’ve created a vector:

 var = R.c("Hello", "beautiful", "world!")

and I want to remove the second element of the vector. From the
documentation it seems like:

 var = var.delete(1)

should work, but it doesn’t. Also, in R there are many ways to filter data
in a vector. For example:

 var[c(1, 2)]
 >> [1]  "Hello"  "beautiful"

this does not work either with Interop

 del = R.c(1, 2)

Is there any way to send a message to ‘[]’?
