Hi, As I pulled down the devel_core image (running boot2docker under OS X Yosemite)
docker run -ti bioconductor/release_core R and then executed > library(AnnotationHub) > hub <- AnnotationHub() and selected the recently integrated GSE62944 TCGA dataset (announced in the latest BioC newsletter, April 2015) > h <- hub[hub$rdataclass == "ExpressionSet"] > h AnnotationHub with 1 record # snapshotDate(): 2015-03-26 # names(): AH28855 # $dataprovider: GEO # $species: Homo sapiens # $rdataclass: ExpressionSet # $title: RNA-Sequencing and clinical data for 7706 tumor samples from The C... # $description: TCGA RNA-seq Rsubread-summarized raw count data for 7706 tum... # $taxonomyid: 9606 # $genome: hg19 # $sourcetype: tar.gz # $sourceurl: http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE62944 # $sourcelastmodifieddate: NA # $sourcesize: NA # $tags: TCGA, RNA-seq, Expression, Count # retrieve record with 'object[["AH28855"]]' and then tried to retrieve the record with either > h[["AH28855"]] or > h[[1]] I received the following error: Error in value[[3L]](cond) : failed to create a 'AnnotationHubResource' instance for hub resource RNA-Sequencing and clinical data for 7706 tumor samples from The Cancer Genome Atlas of class ExpressionSet; reason: ExpressionSetResource is not a defined class Did I do something wrong?
