@tonytonov Vectorizing the code is a good start but Andrie's points above still hold. For me, I would want unused dependencies to also be removed. PRs welcome!

@andrie we should add this to an example/vignette. I'll add it to my to do list, but I don't know when I'll get to it.

digging into this further, it looks like `RandomFieldsUtils` is also a dependency of `spatstat.random`: ```r ── Error (test_mosaicfield.R:4:1): (code run outside of `test_that()`) ───────── Error: The package 'RandomFieldsUtils' is required...
