UPDATE: Thanks to Max Ghenis for updating my R-script which I wrote a while back – the below R-script can now be used again for pulling the number of hits from Google-Search.**theBioBucket***, and kindly contributed to R-bloggers].

GoogleHits <- function(input) { require(XML) require(RCurl) url <- paste("https://www.google.com/search?q=\"", input, "\"", sep = "") CAINFO = paste(system.file(package="RCurl"), "/CurlSSL/ca-bundle.crt", sep = "") script <- getURL(url, followlocation = TRUE, cainfo = CAINFO) doc <- htmlParse(script) res <- xpathSApply(doc, '//*/div[@id="resultStats"]', xmlValue) cat(paste("\nYour Search URL:\n", url, "\n", sep = "")) cat("\nNo. of Hits:\n") return(as.integer(gsub("[^0-9]", "", res))) } # Example: GoogleHits("R%Statistical%Software")p.s.: If you try to do this in a robot fashion, like:

lapply(list_of_search_terms, GoogleHits)google will block you after about the 300th recursion!
