Hi,
how can I parse Google search results? The following code returns
"integer(0)" instead of "1" although the results of the query clearly
contain the regex "cran".
####
address <- url("http://www.google.com/search?q=cran";)
open(address)
lines <- readLines(address)
grep("cran", lines[3])
####
Thanks
Philip
