The error message in my post shows that this is not a quoting problem. I cut and pasted the blog-post code into reply, but in the code I ran, I had replaced the quotes. Bad quotes would return a completely different error message, since R would not be able to parse the function arguments in the first place.
I assume the problem is on Ensembl's end, since the call ' listMarts(host="www.ensembl.org") ' does technically succeed, but the result is empty, thus no marts at www.ensembl.org. Recently Ensembl has changed their default host from www.biomart.org to www.ensembl.org, which broke the biomaRt defaults. Then, they changed the mart names and core dataset names for ensemblgenomes.org marts. I suspect they have changed something yet again.
Hi Ariel,
Sorry for the late reply.
Can you please paste in the exact command line you're running as I can't
reproduce the error message you're getting.
Below is what I get when testing the examples from Ensembl website
(http://www.ensembl.org/info/data/biomart/biomart_r_package.html):
> library(biomaRt)
> listMarts(host='www.ensembl.org')
biomart version
1 ENSEMBL_MART_ENSEMBL Ensembl Genes 84
2 ENSEMBL_MART_SNP Ensembl Variation 84
3 ENSEMBL_MART_FUNCGEN Ensembl Regulation 84
4 ENSEMBL_MART_VEGA Vega 64
> listEnsembl()
biomart version
1 ensembl Ensembl Genes 84

3 regulation Ensembl Regulation 84

5 lafricana_gene_ensembl Loxodonta africana genes

6 choffmanni_gene_ensembl Choloepus hoffmanni genes

The reason that the default host changed in biomaRt was that the
www.biomart.org portal was down and hence the biomaRt developers changed
it to www.ensembl.org.
Can you also please give an example of the changes you mention for the
ensemblgenomes.org marts, as far as I know these have not been modified.
Best regards,
Amonida

Error in useMart(biomart = biomart, dataset = dataset, host = host, verbose = verbose) :
Incorrect BioMart name, use the listMarts function to see which BioMart databases are available
I've discovered the problem is on our end. We have a CentOS 6 sitewide environment, but someone has built the sitewide biomaRt package on an "experimental" server running CentOS7 -- apparently -- because biomaRt will only work on that server. Everywhere else it fails like:
> library(biomaRt)
> listMarts(host='www.ensembl.org')
[1] biomart version
<0 rows> (or 0-length row.names)
Hi Ariel,
Glad you've identified the source of the issue.
Please let us know if you come across any Ensembl related issues in the
future.
Best regards,
Amonida

However, I'm operating on what I thought was a pretty standard version of x86_64 GNU/Linux. I'm not sure what the problem is, but if you found a workaround or have any insights about this problem, I would be grateful to hear!
Trying the above command -- useEnsembl(biomart=“ensembl") -- today on R 3.2.2 and R 3.2.0, it does not work, gives error "Incorrect BioMart name, use the listMarts function to see which BioMart databases are available". Also, using listMarts() with core host "www.ensembl.org" returns a data frame with 0 rows, although "metazoa.ensembl.org" still works. Where do we get the vertebrate marts from now?
Hi Arial
The problem is with the formatting of the command. The first
double-quote in the command is causing the issue. If you replace it with
plain double-quotes the command should work fine:
ensembl_mart_84 <- useEnsembl(biomart="ensembl")
You can also use single-quotes:
ensembl_mart_84 <- useEnsembl(biomart='ensembl')
Hope this helps,
Amonida

@Ariel, I have the same problem too. I am trying to fetch human transcripts and protein domain data via biomaRt and I get the same error "

This is literally blocking me from finishing up my work!
@Amonida, is there any work around for this situation. I am trying to generate lollipop plots using GeneVisR packages lolliplot() command. This requires ensembl annotation. I am running R v3.3.0 on 64bit linux-gnu Ubuntu 14.04.
running R 3.2.2 with biomart 2.28.0, I get the following
> library(biomaRt)> listMarts(host="www.ensembl.org")[1] biomart version
<0 rows> (or 0-length row.names)
> ens <- useEnsembl(biomart="ensembl")
