[R] rrdf package for mac not working

[Ricardo Pietrobon]

Uwe, sorry for the HTML. In answer to your post: I did try to contact
the developer, no response. but a colleague pointed me to a way out
yesterday through the RCurl and XML packages:


library(RCurl)
library(XML)

endpoint <- "http://qcrumb.com/sparql"
query <- "PREFIX sdmx-measure:
<http://purl.org/linked-data/sdmx/2009/measure#> SELECT * FROM
<http://estatwrap.ontologycentral.com/data/lfst_r_lfp3pop> WHERE {?s
sdmx-measure:obsValue ?o.} LIMIT 3"
accept="application/sparql-results+xml"
results <- getForm(endpoint, .params = c(query=query,accept=accept))
results <- xmlParse(results)
results <- xmlRoot(results)[["results"]]
frame  <- xmlToDataFrame(colClasses=c("character","double"), nodes =
xmlChildren(results))
max(frame[2],na.rm=TRUE)
