Dear colleagues, each time I use htmlParse, R crashes or hangs. The url I'd like to parse is included below as is the results of a series of basic commands that describe what I'm experiencing. The results of sessionInfo() are attached at the bottom of the message. The thing is, htmlTreeParse appears to work just fine, although it doesn't appear to contain the information I need (the

I am looking to build simple GUIs based on the R codes I have. The main objective is to hide the scary R codes from non-programming people and make it easier for them to try out different inputs. For example, 1. The GUI will have means to upload a csv file which will be read by the R code. 2. A button to preprocess data (carried out by a R function behind) 3. A button to build some models

Is there a text mining/ NLP package in R that could do text summarization? For example, take a huge text as input and provide a summary of the text. In package tm, summarization is defined more as high frequency terms which is not what I want. I actually want a summary of what is present in the huge volume of text. Any help on a R package would be helpful. Thank you. Ravi -- View this message

Hello All, I am trying to write a routine that loops over some links and parses those links using htmlParse.  The problem is that one of the links may display a pop up window on top of that link's web page.  If there is a pop up, the routine bombs and I get an error message that the url doesn't exist. Does the XML package (or perhaps another package) provide a way to deal with this

Dear R Helpers, I am getting an error message from the try function that I don't understand so I am hoping that someone can help. I am scraping from web pages, but sometimes they disappear.

I have currently a R function that reads a csv file, does some computations, produces some plots and writes a csv file as output. I would like to use HTML forms to make a user interface for calling appropriate parts of the functions (reading csv file, doing computations, displaying plots and writing csv files). Are there are tutorials available that would help me get started?? Thank you. Ravi

I'm using the function htmlParse() in the XML package, and I need a little bit help on error handling while parsing an HTML page. So far I can use either the default way: # error = xmlErrorCumulator(), by default library(XML) doc = htmlParse("http://www.public.iastate.edu/~pdixon/stat500/") # the error message is: # htmlParseStartTag: invalid element name or the tryCatch()
