data.table warning in vignette about chimeraviz

[stianlagstad]

I think 603889b should solve it. Will keep the issue open until Bioconductor has rebuilt the vignette and I can verify that the warnings are gone.

Note to self: Since you did that in the master branch, remember to verify that the warning is gone in the development version's vignette, not the release version. Check it here: https://bioconductor.org/packages/devel/bioc/vignettes/chimeraviz/inst/doc/chimeraviz-vignette.html. When verified, do the same change for the release_3_8 branch.

Looks like that solved it, since the warning is gone from the devel vignette. I'll go ahead and make the same change in the release_3_8 branch.

That should do it!
