R-Bloggers’ Web-Presence

We love them, we hate them: RANKINGS!

Rankings are an inevitable tool to keep the human rat race going. In this regard I'll pick up my last two posts (HERE & HERE) and have some fun with it by using it to analyse R-Bloggers' web presence. I will use number of hits in Google Search as an indicator.

I searched for URLs like this: https://www.google.com/search?q="http://www.twotorials.com" - meaning that only the exact blog-URL is searched.

When checking the results manually I discovered slight deviations in the numbers and admittedly have no clue why this is.. Sorry if any blog is under- overrepresented due to such an error - please report!

Here is the R-script:

require(XML)
library(stringr)
library(RCurl)
library(xtable)

GoogleHits.1 <- function(input)
{
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='subform_ctrl']/*", xmlValue)[[2]]
return(as.integer(gsub("[^0-9]", "", res)))
}

li <- getNodeSet(doc, "//ul[@class='xoxo blogroll']//a")
urls <- sapply(li, xmlGetAttr, "href")

# extract sensible blog urls:
# get ids for those with only 2 slashes (no 3rd in the end):
id <- which(nchar(gsub("[^/]", "", urls )) == 2)
slash_2 <- urls[id]

# find position of 3rd slash occurrence in strings:
slash_stop <- unlist(lapply(str_locate_all(urls, "/"),"[[", 3))
slash_3 <- substring(urls, first = 1, last = slash_stop - 1)

# replace the ones with 2 slashes:
blogs <- slash_3; blogs[id] <- slash_2

# dismiss:
