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. However, some of the pages are blank - and so it throws me an error message when it gets to htmlParse(). The loop then closes out and I

I am using htmlParse from XML library on a paricular website. Sometimes code fails, sometimes it works, most of the time id doesn't and i cannot see why.

Hi, I'm using the XML package to scrape data and I'm trying to figure out how to eliminate the memory leak I'm currently experiencing. In the searches I've done, it sounds like the existence of the leak is fairly well known. What isn't as clear is exactly how to solve it. The general process I'm using is this: require(XML) myFunction <- function(URL) { html

Hi, I am extracting positions data from the marine traffic website. The table has a "Timestamp" column which, in the browser, appears with the format yyyy-mm-dd HH:MM (UTC), e.g. 2017-07-10 14:04 (UTC). When I import the table, the same date "2017-07-10 14:04 (UTC)" appears as "1499696500149969650021 minutes ago", This is the more recent date and time. Older

Can't seem to get the code below working. It gets stuck on line 24 inside the function hm; comments show the line in question. The function hm is called by sapply and is at the bottom of the code. Other stuff above line 24 works correctly including the first couple of lines of the function hm. Should I be using a different apply function or am I doing something wrong with xmlTreeParse ?

Hello, I was wondering if there is a function in R that imports tables directly from a HTML document. I know there are functions (say, getURL() from {RCurl} ) that download the entire page source, but here I refer to something like google document's function importHTML() (if you don't know this function, go check it, it's very useful). Anyway, if someone of something that does this

I can get the QB projections, but I can't get the projections for any of the other positions (e.g., RB). How can I get the RB projections? I'm not sure what the actual website for the RB and other projections is. When I go to
