Rstudio 上的 SPARQL 错误

Question

I'm using the sparql package in Rstudio, to query OMIM through bio2rdf. I have tested my query in yasgui and it works correctly. But from Rstudio he returns the following error:

> qde <- SPARQL(endpoint,query)
Opening and ending tag mismatch: hr line 5 and body
Opening and ending tag mismatch: body line 3 and html
Premature end of data in tag html line 1
Error: 1: Opening and ending tag mismatch: hr line 5 and body
2: Opening and ending tag mismatch: body line 3 and html
3: Premature end of data in tag html line 1

Thanks!!

I had the same problem on RStudio a while ago. This problem was package dependencies. You do install the "sparql" package and its dependencies as below.

install.packages(c("SPARQL", "XML", "RCurl"))

It would be great if you could run the below sample code.

d <- SPARQL(url="http://statistics.data.gov.uk/sparql",
            query="SELECT * WHERE { ?s ?p ?o . } LIMIT 10",
            ns=c('time','<http://www.w3.org/2006/time#>'))
is.data.frame(d$results)
head(d$results)

I hope it useful for you.
