Hello,

I just installed regioneR and tried to run some of the examples in the vignette but they failed. After a fresh install from Bioconductor I did:

library(regioneR)
A <- toGRanges(data.frame(chr=c("chr1", "chr1", "chr1"), start=c(20000, 50000, 100000), end=c(22000, 70000, 400000)))
randomizeRegions(A, genome="hg19")

Error in which(genome == inst_pkgs[, "provider_version"]) : error in evaluating the argument 'x' in selecting a method for function 'which': Error in `[.data.frame`(inst_pkgs, , "provider_version") : undefined columns selected

Here is my sessionInfo():

As a quick update, I installed regioneR fresh on another system and tried the same code from the vignette and received the same error.

After I run the command above, my sessionInfo() includes the BSgenome.Hsapiens.UCSC.hg19 package; I think code (in BSgenome) is assuming that at least one BSgenome package is already installed. Try installing the BSgenome*hg19 package.

Thanks, that was the problem. I suppose this means that BSgenome.Hsapiens.UCSC.hg19 should be a dependency. Unfortunately it's a huge dependency.

Hi rcavalca,

Actually BSgenome.Hsapiens.UCSC.hg19.masked is not a dependency but a suggested package. The idea is that you need at least the BSgenome for the organism you want to work with. If you want to use the mask (so no regions ends up in the centromere, for example) then you should use the ".masked" version of the package.

You are right that it's a huge dependency. We are in the process of creating a small cache of the needed data for the most frequently used genomes and include it with regioneR, so no big download is needed.

It's only needed if you're working on humans and a particular genome build, so it is not a dependency per se but rather a suggested package. It (or the genome for the model or semi-model organism you work on) will be used in many Bioconductor work flows, not just regioneR, so the cost is not so bad.
