filter 16S rRNA sequence from gnenbank file

[fconstancias]

Dear biofiles developpers / users,

I am trying to extract 16S operon from a collection of genbank flat files using R.

I am able to load the file sucessfully:

gbk <- biofiles::gbRecord("~/Projects/ETH/benoit/Bacteroides/200824/GCF_903181445.1_NZ_Bacteroides_fragilis_8E3_BL_hyb_genomic.gbff", 
                          progress = TRUE)

But when it comes to use the biofiles::filter function I can't nake it work:
biofiles::filter(gbk, Feature = "rRNA", product = "16S ribosomal RNA") -> rRNA

biofiles::summary(rRNA)

[[NZ_CAEUHN010000001]]
1857785 bp: Bacteroides fragilis isolate NZ_Bacteroides_fragilis_8E3_BL_hyb, whole genome shotgun sequence.
Error in if (is.atomic(x) || len == 1L && length(nm) <= 1L) { :
missing value where TRUE/FALSE needed

biofiles::getSequence(rRNA)
