similar to: if/else at 1.3.1

Please pardon a novice use question. Is there any way under the Win32 version of R (1.3.0) to change the working directory from the GUI command line? I see the "Change dir" entry under the File menu, but haven't found a corresponding command. Thanks in advance, -jh- ========================================= John M.

"An Introduction to R" says that arithmetic operators coerce logical vectors to numeric vectors. This doesn't seem to be true for unary "-" however: > x <- 1:10 > p1 <- (x > 5) > p2 <- (-p1) > is.logical(p2) [1] TRUE > is.numeric(p2) [1] FALSE Since "==" always does binary comparison, this can lead to some bizarre behavior: > p1

In the windows version of R (1.3.0) is the following a bug, a known problem, or expected behavior: > for (i in 1:2) { + for (j in i+1:3) { + print(j) + } + } [1] 2 [1] 3 [1] 4 ???? [1] 3 [1] 4 ???? [1] 5 ???? > Conversely, the following behaves as expected: > for (i in 1:2) { + k <- i+1 + for (j in k:3) { + print(j) + } + } [1] 2 [1] 3 [1] 3 >

The documentation for sample() describes the optional "prob" argument as "A vector of probabilities of obtaining the elements of the vector being sampled". Both run time behavior and source code (routine FixupProb) suggest that "prob" can be a vector of non-negative, relative weights (i.e. not necessarily normalized). Should the help be updated to reflect this?

Oops... just realized there were a couple mistakes in the question I posted regarding installation of quadprog: 1) The gcc command line is shown wrapped to the next line. Please ignore this. 2) In addition to adding a -Lc:/apps/rw1050/bin option to the command line, I also added -lRblas.

RPART doesn't seem to handle the degenerate case when all training samples are drawn from a single class: > TrainType [1] 0 0 0 0 > TrainDat V1 V2 V3 V4 V5 1 0.6434392 0.5105860 0.3048803 0.3161728 0.5449632 2 0.1710005 0.5973921 0.1267061 0.6146834 0.7299928 3 0.6919125 0.8880789 0.9123243 0.9061885 0.9553663 4 0.3094843 0.6475508

When I try to build/install the quadprog package under R1.50 and NT4 it seems to have trouble finding blas routines. I'm currently using the generic blas routines, rather than ATLAS or some other tuned implementation: > Rcmd INSTALL d:/temp/quadrprog ... gcc --shared -s -o quadprog.dll quadprog.def quadprog.a quadprog_res.o -Lc:/a pps/rw1050/src/gnuwin32 -lg2c -lR

Hi, I'm having trouble with glmmPQL. I'm fitting a 2 level random intercept model, with 90,000 cases and about 330 groups. I'm unable to get any results on the full data set. I can get it to work if I sample down to about 30,000 cases. But for models with N's much larger than that I get the following warning message:

In case this hasn't already been reported or discussed... It took some doing for me to get openssh working on HPUX 11i. The fixes are quite simple. First, one must have the IPV6 package installed: em 512# swlist -l product | grep IPV6 IPV6AA A.01.01.5D IPv6 11i product Second, I have to edit config.h to undefine HAVE_GETADDRINFO. Without IPV6, ssh can't connect

Hi I'm using lme4 to do random effects modelling. I keep getting the following error message: Error in "EMsteps<-"(*tmp*', value = control) : invalid source matrix I get the error when I include more than one random effect in the model, sometime I'm able to get two. I've looked into the variables that cause the problems aren't highly correlated,

Hi, I would like to repsond to a few questions raised in a reply to a question posted by another user on March 17, 2004. The entire message is copied at the end of this email. The relevant questions and statements are as follows: What did you not understand about help(memory.size)? This is also in the rw-FAQ: what in that did you not understand? ... Yes, so try a machine with 2Gb RAM. I

Please pardon an extremely naive question. I see related earlier posts, but no responses which answer my particular question. In general, I'm very confused about how to do variance decomposition with random and mixed effects. Pointers to good tutorials or texts would be greatly appreciated. To give a specific example, page 193 of V&R, 3d Edition, illustrates using raov assuming pure

Hi, I would like to analyze some agilent aCGH copy number files. As a start, I would like to normalize this data. I don't know what is the standard way to do this. Which package is the standard one that people use for this purpose? The chips that I am looking at are the agilent sure print 1M (G4447a) array and a custom chip with similar format. My raw data is a text file with spot locations

Hi, we have this windows application developed internally to keep track of trouble tickets for the IT people. Since I mostly work in the unix/linux environment it would be very nice to be able to use this application with wine. Here is a summary of what i've done so far: installed Wine-20011226.tar.gz copied the program dir from a windows box. Ran the exec (wine Aruser.exe) and recieved

Unfortunately, I blew MySQL away by replacing the MySQL control tables with others and not making a copy of the folder. My data is backed up, so that is not a problem, but I cannot reinstall MySQL and create the mysql directory with the control tables (e.g. user, db, host). I have run "yum remove mysql" and "yum install mysql" and "yum install mysql-server" and
