Hi,
I have tried to use biomaRt (primarily for use in the
GenomeGraphs-package) to retrieve data from the pants_mart_10 -Mart,
and it seems that the service is unstable at the moment (that is, it
works in times but not others). I observed the problem firstly two
days ago and I have not been able to connect today...
Below, I have included some example code to demonstrate the error. I
have read a similar post on the topic, where the problems seemed to
have been at the server-side and not the user-side (?).
Any suggestions, in case I have to troubleshoot on my side?
Thanks a lot for any help.
Best, Sam
