Estou usando o pacote sparql no Rstudio, para consultar o OMIM através do bio2rdf. Eu testei minha consulta no yasgui e funciona corretamente. Mas do Rstudio ele retorna o seguinte erro:

> 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

Obrigado!!
