The molecular signatures database (MSigDB) in R

I'm trying to use the msigdb package, but I can't seem to access the EH9632 resource. When I call msigdb::getMsigdb(), it only fetches up to EH8300. From what I understand in the official vignette, the most recent version of MSigDB should be v 1.9.x, but my setup seems to be defaulting to older versions (e.g., 1.14.0 instead of 1.19.x). I've tried updating the package and Bioconductor version, but I haven't been able to force access to the EH9632 resource. Code I'm using:

if (!requireNamespace("BiocManager", quietly = TRUE))
      install.packages("BiocManager")

BiocManager::install("msigdb", force = TRUE)

packageVersion("msigdb")

library(msigdb)   
library(ExperimentHub) 
library(GSEABase)     

eh <- ExperimentHub()

msigdb_records <- query(eh, "msigdb")

print(msigdb_records)

Any help on how to access the correct version or force download of EH9632 would be greatly appreciated!

Hi, with the current version of Bioconductor and msigdb I was able to access the EH9632 dataset you requested. I'm sharing with you the versions I have and the commands I used. Try with these versions as well. I’m also attaching the dataset in case you’re unable to access it if necessary.

I hope this helps,
