Hi All, I would like to use anonymous cvs, but it appears not to be working (again?). There was a discussion back in Jan-Feb about whether to continue supporting it, but it seemed that Tony Rossini got it working and the discussion left off there. Did someone decide to disable it, or is it just not working properly? Here's the details: $ cvs -d

Dear R users, I ran into this curious problem: > d <- rnorm(100) > d.density <- density(d) > sum( d.density$x * d.density$y) [1] 2.517502 Admittedly the method of computing the mass under the density curve at line 3 is crude. But 2.5 is pretty far from 1, the value it should be. I tried a few other dataset and got similar result. Am I missing something obvious? Or is the return

hi, Are there any alternative authentication methods for Samba? Other thank the smbpasswd file? I'd like to do PostgreSQL or mySQL. Why? Because I can do Exim/IMAP/POP3 Apache/Zope with SQL, if I could do Samba it would wrap it up into one nice DB for authentication. It does not have to be much, just the ability to get the data from a SQL query rather than a flat file query. Anyone

As a user of only R, I don't use much of the potential of ESS and Emacs. Without entering a religious feud, is there any reason I should use XEmacs rather than my current GNU Emacs? (I looked on the XEmacs site, but I didn't understand the programming issues they were talking about (over my head).) Martin Henry H.

Dear R experts, Sorry, I am resending this, since I have not received this mail myself for the past 5 hours. I saw a similar question dated July 2. But there is no answer to it. Does anybody have a solution to it? I am using window NT, and the R version is 1.5.1, the SJava package is the binary version SJavaWin_0.62-8.zip. Here are the error message: > library(SJava) > .JavaInit()

Hi Folks, I'm currently looking at missing data/imputation methods (including multiple imputation). S-Plus has a "missing data library". What similar resources are available within R? Or does one roll one's own? Best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding at nessie.mcc.ac.uk>

Hello everyone, Thanks to all who offered suggestions after my initial query to the list. I've been busy trying to absorb the docs as fast as possible, but this little thing has me stumped for the moment. I'm creating a random sample of 100 item and saving it to a vector named 'iq'. I'd like to create a second vector (iq_prime, say) by adding 20 to each element of the

Dear list members, I've had helpful feedback from a number of people, several of whom experienced some problems getting my XEmacs/ESS configuration files for Windows to work properly. I will, of course, make changes based on this feedback, but the following information may be of use in the interim: (1) It's clear that my instructions and installation procedure were insufficiently

Sam Rushing's Python extension 'calldll' will supposedly give me access to any DLL, and presumably R.DLL in particular, from Python. I have no experience manipulating DLLs as yet. I am learning Python. I can't find any simple step-by-step instructions on how to get done what I want to do. Does anyone have experience with this? Is there a better way? Of course, one can use

seek(zz,where=NewPosition) returns the OldPosition of connection zz (of the appropriate "pointer", i.e. read or write). Currently, the docs have: > Details: > > `seek' with `where = NA' returns the current byte offset of a > connection (from the beginning), and with a positive `where' > argument the connection is re-positioned (if possible) to

could we add an argument to suppress printing of levels for print.factor()? i.e.: print.factor <- function (x, quote = FALSE, print.levels = TRUE, ...) ## MODIFIED { if (length(x) <= 0) cat("factor(0)\n") else print(as.character(x), quote = quote, ...) if (print.levels) { ## ADDED cat("Levels:

Thanks to Tony Plate for letting me know what the abbreviate.arg option does. I think this could be made more flexible (I.e. =TRUE, =FALSE, =#, where # would be passed to the abbreviate min.length argument). But it follows the example I was given. "print.factor" <- function (x, quote = FALSE, max.levels=5, print.levels = {if (max.levels==0) FALSE else TRUE},

Is the anonymous CVS repository for R presently broken? There haven't been many updates coming through and the repository files seem to differ significantly from the rsync version of R-devel...

I've been doing some prototype simulations in Python, and my plan at first was to pass the results off to R, but now I would like to make more of an integrated use of the R routines. I'm curious about the use of libR.so, but I'm uncertain, still after having looked through the documentation 'Embedding R in Other Applications' and 'Writing R extensions' how I can

Hello R Pioneers, I sometimes use R on a dual CPU PC runing Linux and find that only 1 CPU is used even when no other user/process competes for resources. Can we make R uses both CPUs to have the job done sooner? I know this is probably asking too much for something that is free. Has anyone else thought about it? Thanks. Ming Chow
