Hi Mannau. Thank you for your package, I am trying to use your package in my research project, but I get the following error: googlenews <- WebCorpus(GoogleNewsSource("Microsoft"))

Unknown IO errorfailed to load external entity "http://news.google.com/news?hl=en&q=Microsoft&ie=utf-8&num=100&output=rss"

Error: 1: Unknown IO error2: failed to load external entity "http://news.google.com/news?hl=en&q=Microsoft&ie=utf-8&num=100&output=rss"

The erros comes from this function parser <- function(cr) { tree <- parse(cr, type = "XML", asText = FALSE) nodes <- xpathSApply(tree, path = "//item") xmlns1 <- lapply(nodes, newXMLNamespace, "http://purl.org/dc/elements/1.1/", "dc") nodes } The parse function create the error.

Thanks,

How do you then check all the news as being positive or negative?
