Hello, I do not have an account on R Bugzilla, so I will post my bug report here. I want to report a very old bug in base R *source()* function.

For some reason if the UTF-8 script is containing cyrillic letter *"?"*, the script execution is interrupted directly on this letter (btw the same scripts are sourcing

I am writing bindings to the neural network simulator SNNS. At present I have used only .C interface, now I'm studying .Call interface.

I am writing a package, which contains several functions and variables. The variables are for internal use by functions. Functions are ment to be callable by a user. However, the function cannot access these variables. The package contains only R code, and was created using package.skeleton package.skeleton(name="ac9", list=c(ls(pattern="(AB2)|(ac9)"),

It seems, I don't understand something, or there is a bug in R. I have made some experiments after my yesterday post about using "=" with -e switch to the Rscript. Now, I've found: (1) C:\users\wl\trainings\r>rscript --verbose -e "mean(x=1:3)" running 'C:\Program Files\R\bin\Rterm.exe --slave --no-restore -e mean(x=1:3)' Error in -args : invalid

Hello dear R-help mailing list. I wish to be able to have htmlParse work well with Hebrew, but it keeps to scramble the Hebrew text in pages I feed into it. For example: # why can't I parse the Hebrew correctly? library(RCurl) library(XML) u = "http://humus101.com/?p=2737" a = getURL(u) a # Here - the hebrew is fine. a2 <- htmlParse(a) a2 # Here it is a mess...

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'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()

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.

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

Hi, I'm trying to download some data from the web and am running into problems with 'embedded null' characters. These seem to indicate to R that it should stop processing the page so I'd like to remove them.

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
