[R] Using R to convert RDF/XML to

[Evans, Richard K. (GRC-H000) via R-help]

Hello R community,

I am a novice R enthusiast trying to use R to convert an RDFdump file [1] from 
Semantic Mediawiki [2] into something that can be natively imported by GePhi 
[3] for graph visualization. The SMW RDFdump file is formatted as RDF/XML and I 
have found the R package "rdflib" [4] 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: 
library(rdflib)
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.

[R] how to ref data directly from bls.gov using their api

[Evans, Richard K. (GRC-H000) via R-help]

Hello, 

I'd like to generate my own plots of various labor statistics using live data 
available at https://www.bls.gov/bls/api_features.htm

This is 10% an R question and 90 % a bls.gov api query question.  Please 
forgive me for making this request here but I would be truly grateful for 
anyone here on the R mailinglist who can show me how to write a line of R code 
that "fetches" the raw data anew from the bls.gov website every time it runs. 

Truest Thanks,
/Rich
