I'm currently stuck, due to examples not working, so I need to postpone this.
Which examples are not working?
@Piiit I tried to set up an R query to our sparql endpoint but it fails with some error that I can not understand.
@stefanodavid OK, now I understand. It was not obvious that you were talking about sparql, I thought you were refering to the bzar library. Do you want to write to Ontopic about this issue?
Changed the title to be clearer... maybe you need to rephrase it again... sounds strange now ;-)
I forwarded you an email with code & errors, FYI. I probably contact Peter next week if I don't find the issue (which is the most probably case, I have very limited R knowledge)

FTFY :-)

Strange, I do not have any emails regarding that topic... let me check my quarantine
It's the "usual" problem... It should have been sent right now Apr 9 17:07:59 mail postfix/smtp[25338]: 60E505E214A: [ cut ] delay=593, delays=592/0.04/0.34/1.1, dsn=2.6.0, status=sent (250 2.6.0 [ cut] 12676 bytes in 0.139, 88.661 KB/sec Queued mail for delivery)
@stefanodavid Got it now, have you resend it?
No, my emails are now all deferred at the first trial and sent at the second attempt. :-(
Hope it will get better with those email issues :-/
I will have a look at R/sparql if I find the time, but not so soon I fear... maybe it is faster to talk to Peter first.
offtopic about the mail issue: This is called greylisting and it's a widely used anti-spam mechanism (https://tools.ietf.org/html/rfc6647). So it cannot get better per definition regarding the first vs. second attempt of mail delivery.
Yes, they evolved from rejecting TLS connections to greylisting, in a coouple of months perhaps they'll accept my emails at the first attempt :P
@mrabans @Piiit I received an answer from Peter, the R script works, it was a stupid mistake on my side. I will complete this howto at latest on Monday morning.
@stefanodavid Great, good to know
In this issue I am adding a generic R tutorial which uses R's SPARQL package. In the future, I can consider to add an example using bzar (I think this is not a priotity ATM).
Since ODH data can now be accessed using the R framework, we need an howto with an example of data access.
