Package not working anymore? about citecorp HOT 3 CLOSED

Looks like some functions work, but not others.

library(citecorp)
doi1 <- "10.1108/jd-12-2013-0166"

oc_coci_cites(doi1) # works
oc_coci_refs(doi1)  # works
oc_coci_meta(doi1)  # works

These use the REST endpoint.

But these rely on SPARQL:

oc_doi2ids(doi1)  # 0 columns, 0 rows

The same type of query pasted onto the https://opencitations.net/meta/sparql sandbox seems to work:

PREFIX datacite: <http://purl.org/spar/datacite/>
  PREFIX literal: <http://www.essepuntato.it/2010/06/literalreification/>
  SELECT ?paper ?pmid ?pmcid ?value
  WHERE {
    {
      ?paper datacite:hasIdentifier [
          datacite:usesIdentifierScheme datacite:doi ;
          literal:hasLiteralValue ?value
      ] .
      OPTIONAL {
        ?paper datacite:hasIdentifier [
          datacite:usesIdentifierScheme datacite:pmid ;
          literal:hasLiteralValue ?pmid
        ] .
      }
      OPTIONAL {
        ?paper datacite:hasIdentifier [
          datacite:usesIdentifierScheme datacite:pmcid ;
          literal:hasLiteralValue ?pmcid
        ] .
      }
    } .
    VALUES ?value { "10.1093/biomet/80.3.527" }
  }

returning the following output

{
  "head" : {
    "vars" : [ "paper", "pmid", "pmcid", "value" ]
  },
  "results" : {
    "bindings" : [ {
      "value" : {
        "type" : "literal",
        "value" : "10.1093/biomet/80.3.527"
      },
      "paper" : {
        "type" : "uri",
        "value" : "https://w3id.org/oc/meta/br/06250321084"
      }
    } ]
  }
}

But when the R package does it, the results$bindings are empty. Will try to debug this: maybe it is calling the wrong endpoint or something.

@rkrug I have just pushed a fix, which seems to work now for oc_doi2ids("10.1097/igc.0000000000000609") and other examples I tried.

Neither oc_pmid2ids nor oc_pmcid2ids produce results for the examples in the Examples section of the documentation, but they give the same output as the sandbox, so that appears to be a separate issue.

Thanks - I actually need the function oc_coci_refs() which is still not working. I think it is a similar issue.
