Edit Question
Title
Body
As an intern in an economic research team, I was given the task to find a way to automatically collect specific data on a real estate ad website, using R. I assume that the concerned packages are XML and RCurl , but my understanding of their work is very limited. Here is the main page of the website: http://www.leboncoin.fr/ventes_immobilieres/offres/nord_pas_de_calais/?f=a&th=1&zz=59000 Ideally, I'd like to construct my database so that each row corresponds to an ad. Here is the detail of an ad: http://www.leboncoin.fr/ventes_immobilieres/197284216.htm?ca=17_s My variables are: the price ("Prix"), the city ("Ville"), the surface ("surface"), the "GES, the "Classe énergie" and the number of room ("Pièces"), as well as the number of pictures shown in the ad. I would also like to export the text in a character vector over which I would perform a text mining analysis later on. I'm looking for any help, link to a tutorial or How-to that would give me a lead over the path to follow.
