I am trying to use AnnotationDbi to map Ensembl IDs to GeneIDs for an RNAseq experiment, but I keep coming up with an error.

Starting from a new R session, I install and load the genome package.

>BiocManager::install("BSgenome.Hsapiens.UCSC.hg19")
>library(BSgenome.Hsapiens.UCSC.hg19)
> ls("package:BSgenome.Hsapiens.UCSC.hg19")
[1] "BSgenome.Hsapiens.UCSC.hg19"

However, when I try to see what keytypes or columns are available, I get an error:

> keytypes(BSgenome.Hsapiens.UCSC.hg19)
Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function 'keytypes' for signature '"BSgenome"'

> AnnotationDbi::columns(BSgenome.Hsapiens.UCSC.hg19)
Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function 'columns' for signature '"BSgenome"'

I cannot proceed with mapping the GeneIDs if the keys and columns functions do not work. Is there something I'm missing? Any advice would be greatly appreciated!

The BSgenome packages provide information about the genome itself (e.g., the sequences), which doesn't include annotations for the genes. For mapping between annotations, you want either an OrgDb or an EnsDb object.

These days, a GeneID is colloquially inferred to be an NCBI Gene ID (what used to be called an Entrez Gene ID in the olden days). If that is what you want to do, I would caution against it. But maybe what you really want is the HUGO symbol? In which case you can use an EnsDb. This can be a bit tricky since Ensembl updates things relatively often, so you may have to search a bit to get the right one. I usually do something like this:

> library(AnnotationHub)

> hub <- AnnotationHub()
  |===========================| 100%

snapshotDate(): 2023-04-25
> query(hub, c("homo sapiens","ensdb"))
AnnotationHub with 25 records

#   taxonomyid, genome,
#   description,
#   coordinate_1_based,
#   maintainer, rdatadateadded,
#   preparerclass, tags,
#   rdatapath, sourceurl,
#   sourcetype 
# retrieve records with, e.g.,
#   'object[["AH53211"]]'

## here I just fake up some IDs for an example

Yes, I meant I wanted to generate the HUGO symbols for each gene, so I'll go ahead and use EnsDb. I am getting the same error when I use this database though. It installs fine, but I cannot use arguments such as 'select' or 'keys' etc.

It looks like you loaded some tidyverse package(s) after having loaded AnnotationHub. In which case you will have to use the qualified name of the function.

> hub <- AnnotationHub()
snapshotDate(): 2023-04-25
> ens106 <- hub[["AH100643"]]
