Hi, beginner to R and was having some problems scraping data from tables in html using the XML package. I have included some code below. I am trying to loop through a series of html pages, each of which contains a single table from which I want to scrape data.

I''ve generally done this in my controller, where I can catch exceptions and

Hey guys, I'm a server admin working on some high-availability web server setups with Amazon's EC2. We're running Gluster to keep our assets sync'd up between regions globally using replicated volumes with one brick in each geographic region.

Hello, I would like to scrape some html tables from a web page and convert them to a data.frame so I can perform further analysis. Could anyone tell me the best way to do this?

I see that if I use the date_select helper in my view, then in the generated page, my selects are named obj[datetime_field(1i)] (and 2i and 3i for the other parts). These auto-populate the date portion of my datetime_field. I have another datetime field that I''m presenting the time from and I would like to use a similar scheme to autopopulate it. Currently, I''ve used the

Hi, I''ve just started toying with Rails and AJAX, so forgive me if this is a bit of a stupid question. I''m trying to populate a select field when the value of another select field is changed.

These will be updated infrequently and are ''configuration'' data, so I''m not sure its worth constructing an interface to do this in the deployed app. Seeing as
