Error in biomart connection

Question

[shivangi.agarwal800]

Hi

When using following code in R, I am getting error

lolliplot(mutation_data, fillCol="mutation_type", labelCol="amino_acid_change", proteinColour = "#ffffff", paletteB ="green", txtSize=3, txtAngle=20, host="dec2013.archive.ensembl.org")

Using the following host: dec2013.archive.ensembl.org for biomaRt queries to change the ensembl annotation version alter this parameter!
Querying biomaRt for transcript sequence
Request to BioMart web service failed.
The BioMart web service you're accessing may be down.
Check the following URL and see if this website is available:
http://dec2013.archive.ensembl.org:80/biomart/martservice?type=registry&requestid=biomaRt
Error in if (!grepl(x = registry, pattern = "^\n*<MartRegistry>")) { : 
  argument is of length zero

How to solve this?

Origin of error is clear Request to BioMart web service failed.. Does that suggested link work for you?

That particular Ensembl archive is no longer available. You can view the list of available archives by following the link in the error message (you'll be redirected to an appropriate page) or by using the listEnsemblArchives() function in biomaRt e.g.

> biomaRt::listEnsemblArchives()
