We would like to announce the availability on CRAN of a new package: RUnit It contains a unit testing framework strongly inspired by Javas popular JUint package. In addition it contains some functionality to investigate the degree to which some function is covered by a test suite. The main aims of the package are - to support a development style where test cases are written and constantly

I am looking to fit one or more latent categorical variables to data that is a mixture of categorical and continuous variables. Factor analysis would work for continuous data, latent class analysis for categorical data. I understand that in a package such as MPlus I could perform a single analysis of both data types. Are there similar routines available in R? Stuart -----Original Message-----

Dear Ingmar & Dave, Thanks a lot for your help and sorry for the late reply. Finally, I've found a way to separate the mixture of distributions (empirically). But the gamlss package looks great, I'm sure it will help me during my further studies.

Dear all, I am trying to read in big amounts of data with scan. It's only one variable, numeric values, separated by tabs,.. and it's many of them. So I was thinking that I could use the skip option and read in 100000 values at a time - but skip doesn't work, probably because I don't have line breaks in the txt file. So any value specified for skip makes the scan function jump to

Dear all, I am attempting to model some one-dimensional data using a mixture model of non-central Student's t distributions. However, I haven't been able to find any R package that provides this functionality. Could there be a way to "manipulate" the EM algorithms from the mixdist or mixtools package to fit the model, or do you have any other suggestions? If anyone could help

Hi, trying to install a package containing C code and requiring non-default configure argument settings the incantation (this has worked for R <= 2.8.1 on the same architectures) R CMD INSTALL --configure-args="--with-opt1 --with-opt2" packname does always result in a warning Warning: unknown option '--with-opt2' and consequently the option is ignored. Reverting the order

Hi! I'm puzzled by the return value of ifelse consider x<-integer(0) ifelse(is(x, "character"), paste(x), x) [1] NA whereas if (is(x, "character")) return(paste(x)) else x [1] integer(0) or x<-integer(1) ifelse(is(x, "character"), paste(x), x) [1] 0 work as I had anticipated. Is this correct behaviour? Regards, Matthias >sessionInfo() R

Hi! >getNamespaceExports("base") Error in ls(NULL, all = TRUE) : using 'as.environment(NULL)' is defunct getNamespaceExports function (ns) { ns <- asNamespace(ns) if (isBaseNamespace(ns)) ls(NULL, all = TRUE) else ls(getNamespaceInfo(ns, "exports"), all = TRUE) } <environment: namespace:base> One possible way to fix this could be

Hi, we noticed that since some time after Aug 24th the daily snapshots provided on ftp://ftp.stat.math.ethz.ch/Software/R/ no longer have their default tarball file name but dropped the date stamp, i.e. R-devel_.tar.bz2 Same for R-patched snapshots. Could one of the maintainers please take a look. We rely on the default naming convention for automatic builds. Regards, Matthias --

Hi! Is it possible to avoid this error condition by specifying a command line option? I haven't found an obvious one in the manual. Background: We are using rsync for a live backup of our home directories. Emails are stored in Maildir format within the homedirectories. The rsync process is running for some time and in the meantime emails get deleted because users still have IMAP access. The

Hi, since a couple of days ago I see failures when using R CMD INSTALL -l lib path-to-src/pkg.tar.gz This occurs in automated library updating via a shell script and is caused by the immediate preceding call to leave an 00LOCK folder even though the package installation of that call succeeded. This occurs at random (no obvious/systematic correlation to package name or or such) and only for

Dear all, I tried help.search("karber") and RSiteSearch("karber") and RSiteSearch("*karber*") to find whether the (trimmed) Spearman-Karber method for LD50 evaluation in toxicity data (e.g. according to Hamilton 1977) has been implemented in R. Or does this method feature under a different name? Of course logit and probit are doable, but Spearman-Karber seems to

Hi, after updating R 2.5.0 devel yesterday we today observed many new unexpected failures in our daily package build and test system runs, which can be traced to recent changes in the implementation in try() (as noted in NEWS). Investigating this new implementation I come across an issue in conjuntion with using S4 classes and methods. try(expr) does not return an object with attribute

Hi, I encounter a problem with method dispatch with S4 classes, using the 'sealed' parameter in setClass. See that example below: setClass("X",representation(x="numeric"),sealed=TRUE) setGeneric("foo",function(x) standardGeneric("foo")) setMethod("foo",signature("X"),function(x) print("foo(X)")) x <-

Hi! I am currently testing a setup with dovecot's lda, the cmusieve plugin, pysieved and the avelsieve plugin for squirrelmail. The issue I am stumbling upon is that avelsieve is generating folder names including the namespace prefix when creating "fileinto" rules. E.g.: A rule: If the header "Precedence" contains "bulk", then file it into the folder

Hi! We are running dovecot-imapd on Debian sarge out of the backports.org packages (version 1.0.rc15-1~bpo1). We have ~ 80 clients using secure IMAP. I understand that imap-login has to run for every SSL connection. Thus I already increased the max value for the number of imap-login processes. But unfortunately dovecot is unresponsive from time to time. Where can I tune the installation? Do I

Hi, Actually I am facing a similar problem. I would like to fit both an ordinary (symmetric) and a non-central t distribution to my (one-dimensional) data (quite some values.. > 1 mio.). For the symmetric one, fitdistr or funInfoFun (using fitdistr) from the qAnalyst package should do the job, and for the non-central one.. am I right to use gamlss(x ~ 1, family=GT()) ? Anyway, I am a little

We're running rsync 2.5.7 on a Windows2000 server, in combination with cygwin/ssh. The server who receives the data is a Linux server. The amount of data from the Windows server is about 100 Gb. Represented by 532.000 files of different nature. Mostly doc, ppt and xls files. It takes about 2 hours to create only the file list. Is the amount of data/files to big, should I segmentate the

Hi all, I've been attempting to fit a logistic glmm using glmmPQL in order to estimate variance components for a score test, where the model is of the form logit(mu) = X*a+ Z1*b1 + Z2*b2. Z1 and Z2 are actually reduced rank square root matrices of the assumed covariance structure (up to a constant) of random effects c1 and c2, respectively, such that b1 ~ N(0,sig.1^2*I) and c1 ~
