Hello R community,
I am a novice R enthusiast trying to use R to convert an RDFdump file  from Semantic Mediawiki  into something that can be natively imported by GePhi  for graph visualization. The SMW RDFdump file is formatted as RDF/XML and I have found the R package "rdflib"  and am able to read the RDF/XML file into R as an "rdf" object, but it is not clear to me how to save the "rdf_serialize" function output to a new file.
What I have so far is:
NewRDF <- tempfile( "TempFile", fileext = ".nq" )
MyRDF <- rdf_parse( "MyRDFdumpFile.txt" )
rdf_serialize( MyRDF, NewRDF, format = "nquads" )
write_nquads( MyRDF, NewRDF )
..but this results in the error: "Error: object of type 'closure' is not subsettable"
I will keep struggling with this to learn what I need to learn, but any advice to help make quick work of this would be much appreciated.
Thank you in advance.
