This leads to the following when loading the package:

[1] biomart version
<0 rows> (or 0-length row.names)

a month ago everything was fine:

> listEnsembl()
     biomart               version
1    ensembl      Ensembl Genes 84
2        snp  Ensembl Variation 84
3 regulation Ensembl Regulation 84
4       vega               Vega 64


I'm using biomaRt with easyRNASeq to annotate my RNA-Seq data.


A suggested workaround is:

listMarts(host = "")


but that doesn't work for me:

> listMarts(host='')
[1] biomart version
<0 rows> (or 0-length row.names)

What shall I do? This is quite frustrating. Session Info below. Do I need to upgrade to R 3.3 and biomart 2.28???

YES! You always need to upgrade to the newest versions. If there are changes to the Biomart at Ensembl, you cannot expect old versions of biomaRt to be upgraded to address that. The only version that is expected to work flawlessly (and the only version that is supported) is the current version.
