Hi R useRs: How can I generate a random sample from Maxwell Distribution in C language? Since I know the function rmaxwell {VGAM}, I tried the function r2c {r2c}. But I still cannot find the source code. Thanks for your kind help. RegaRds, 2010-03-12 Randel [[alternative HTML version deleted]]

I have problems with Rpad and R 2.10.0 (Windows XP and Windows 7, browser is Firefox) Just starting Rpad by library(Rpad) Rpad() opens the browser and displays the .html files and the .Rpad files in my home directory, but these files do not have links and are not clickable. Doing the same in R 2.9.2 gives clickable links in the browser. Furthermore, in both cases an empty graphics window

Hi all, It is recommended in ?'if' that we use 'else' right after '}' instead of starting a new line, but I noticed deparse() will separate '}' and 'else' when the 'if...else' clause is used inside {...} (e.g. function body). Here is an example: ## if/else inside {} > cat(deparse(parse(text='function(){if (TRUE) {1} else {2}}')),

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()

Hi: Is there a way we can set up WINBUGS to run 100 simulated datasets on the same model and output results? Or do we have to call in each dataset at a time and repeat the process 100 times manually? Thanks Anamika [[alternative HTML version deleted]]

I have a function: source_dir <- function(path, pattern = "\\.[rR]$", chdir = TRUE) ... documented with ... \usage{source_dir(path, pattern="\\.[rR]$", chdir=TRUE)} ... But I get Codoc mismatches from documentation object 'source_dir': source_dir Code: function(path, pattern = "\\.[rR]$", chdir = TRUE) Docs: function(path, pattern =

Hi, I want to compute the pairwise correlation for about 10,000 genes. In Matlab there is a function called 'pdsit' that can do this very efficiently. I am wondering is there a similar function in R? Thanks, RT Ye.

This is kind of a dumb question: I know you can use isdebugged() to find out if a specific function is flagged for debugging, but is there a way to list all the functions that are flagged for debugging? Thanks, Andrew [[alternative HTML version deleted]]

Hello. I've been working an a binding between OCaml and R (i.e. calling R from OCaml, mostly). See below for a taste of it. I'm currently wondering how to load a given R package silently. I tried require(xts, quietly = TRUE) but I still get some ugly output. Is it possible to squeeze off this output on stdout? All the best, Guillaume Yziquel. > yziquel at seldon:~$

Hello, I would like to implement the feature request described here: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=13287. I think this is a very worthwhile feature. However, I need just a little push in the right direction. When I added either a new command or change the old one to use eqnarray as proposed, the "\\" newline characters were not properly passed to latex - even

Sorry, I listed the wrong package in the header of my previous post! >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Dear List, has anyone of you experienced a significant increase in the time it takes to parse an URL via "htmlTreeParse()" when this function is called

Dear R helpers,   I understand that this is absolutely unprofessional on my part and this group doesn't entertain such things. I have been associted with this group since last 1 and half years and have been immensely benefited by the noble service rendred by many R helpers.   So I take this opportunity to thank all of you and wish you all   "MERRY CHRISTMAS".   I sincerely apologize

I'm seeing what looks to me like odd behaviour when I use na.omit on a simple "length" function, as follows. > sno [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 > a [1] 0 1 0 0 1 1 0 0 0 0 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 > b [1] 1 1 0 1 1 1 0 0 NA 0 0 0 NA 0 1 NA 0 1 0 0

 Hi, I want to be able to save the following animated plot as a flash.  There are ultimately 6 plots, but when I run this and save it as a flash all I get is the last (6th) plot, not all six different plots in order by "year".  I’ve tested the flash commands and they work; so it has to be my function code. I am guessing that the problem has something to do with overlaying the plot

Dear friends, I am testing glm as at page 514/515 of THE R BOOK by M.Crawley, that is on proportion data. I use glm(y~x1+,family=binomial) y is a proportion in (0,1), and x is a real number. I get the error: In eval(expr, envir, enclos) : non-integer #successes in a binomial glm! But that is exactly what was suggested in the book, where there is no mention of a similar warning. Where am I

I tried to use BATCH command to run an input file (a simple text file) which contained a few R commands.

I wrote the Rcpp library and the RcppTemplate package to make it easier for developers to contribute packages to the R community. In addition to providing detailed documentation on package creation it provides a clean object mapping between R anc C++ that helps developers to implement packages that benefit from the performance of C++ and the flexibility of R. The package named 'Rcpp' was
