Jens I'm not sure what you intend by "predefined assumptions". 1. If you merely want to conduct an exploratory rather than confirmatory analysis for the relevant paths, there are ways within SEM to do this. (In this case you could use John Fox's SEM package). 2. If you do not wish to assume multivariate normality, then you may use a variety of alternative (to maximum likelihood)

Hi all, I had a look at the interprocedural optimizer. In my opinion the routine 'GlobalOpt::ProcessInternalGlobal' is a little bit to conservative. It removes global variables if the only routine using this variable is main. Typically this condition is valid only for very few global variables. Here is a code snippet containing the test before the transformation: file:

I've noticed what I think is curious behavior in using 'sub(fixed = TRUE)' and was wondering if my expectation is incorrect. Here is one example: v <- paste(0:10, "asdf", sep = ".") sub(".asdf", "", v, fixed = TRUE) The results I get are > sub(".asdf", "", v, fixed = TRUE) [1] "0"

The 'cacher' package contains a set of routines for caching statistical analyses. The idea is that an analysis stored in a file (say, 'foo.R') is run and the results of the evaluated expressions are cached in a database. These cached results can subsequently be packaged up and distributed over the interweb. I've just uploaded to CRAN version 0.1-2 of the 'cacher'

When --partial-dir is used rsync creates new or updated files inside a temporary dir. For example the new version of some/path/file is created in some/path/<partial-dir-name>/file and later moved. What happens if a new directory is created? If some/path/newdir/newfile is to be copied, is it done in some/path/<partial-dir-name>/newdir/<partial-dir-name>/newfile? Or is newdir

[I originally emailed this to Friedrich Leisch but got no response and I just wanted to make sure it made it in before release.] While working with Stangle(), I noticed a problem when using 'split = TRUE'. Particularly, when there are two chunks where one chunk's name is a prefix of another chunk's name, then the two chunks will be written to a single file rather than two

I've noticed a change in the way grep() behaves between the 1.9.0 release and a recent R-patched. On 1.9.0 I get the following output: > x <- dget(file = url("http://www.biostat.jhsph.edu/~rpeng/names.R")) > length(grep("^l\\w+tmean", x, perl = TRUE, value = TRUE)) [1] 84 And on R-patched (2004-06-11) I get > x <- dget(file =

I noticed the following peculiarity with `serialize()' when `ascii = TRUE' is used. In today's (svn r37299) R-devel, I get > set.seed(10) > x <- rnorm(10) > > a <- serialize(x, con = NULL, ascii = TRUE) > b <- unserialize(a) > > identical(x, b) ## FALSE [1] FALSE > x - b [1] -3.469447e-18 2.775558e-17 -4.440892e-16 0.000000e+00

Hi (Roger), I saw the announcement of filehash v2.0 and the sentence "This development has lead to better file locking for concurrent access and faster reading and writing of data in general" caught my attention. What kind of file locking do you refer to here? I am looking for a mechanism that can be used to lock files for reading and/or writing, and I'd love to have a cross

I've been very interested in these discussions and uses of rsync as a "clone" of Time Machine. A couple of things have been keeping me from a fully automated solution. I'd like to eliminate the need for Samba/NFS mounts of any kind, because they have proven to be unreliable for me and under some operating environments (Cygwin) it breaks --link-dest. In most of the articles

When I build R-devel (or the alpha snapshots) on a system without makeinfo >= 4.7, I get a warning about not being able to build HTML/Info help pages after running 'configure' (but 'make' runs smoothly and there are no errors). However, when I run 'make install' I get an error, something like make[2]: Entering directory

Dear John, Dear Joseph, Thank you for your quick answers and the pointer to semnet. I try to clarify on my assumptions: - yes, I am willing to assume multivariate normality - no, I don't want to assume a single factor model - I assume there is an unknown number of factors, and I do not know which items belong to which factors but I still want to estimate single item reliabilities Is this

Hi Guys, I am new to R and just trying to write a small script to automate a couple commands. But I run into the setwd(): cannot change working directory. I googled a little bit and tried all fixes/suggestions with no success. Basically I have a script that works from inside a directory with my data (/home/sean/Rtest/Data01). Now I want to modify the script to make it run from the upper directory

In R 1.9.0 on Solaris/Sparc when I run, for example, install.packages("gregmisc", "~/R-local/lib"), instead of installing the `gregmisc' package in the directory /users/student/rpeng/R-local/lib the package gets installed in /users/student/rpeng/\~/R-local/lib, so the directory \~ is created in my home directory. This doesn't happen to me on Linux or Windows so I

Currently, rsync --delete -avvn test1/ test2/ --existing will give output such as: not creating new file "newdir" not creating new file "newdir/newfile" not creating new file "newdir/subdir" It would make more sense if it said: not creating new directory "newdir" not creating new file "newdir/newfile" not creating new directory

Are the functions 'R_Unserialize' and 'R_InitFileInPStream' allowed to be used in R packages? I guess I'm just not clear on the implications of this comment in 'Rinternals.h': /* The connection interface is not yet available to packages. To allow limited use of connection pointers this defines the opaque pointer type. */ I have a function in the

Hi, in this thread: https://lists.samba.org/archive/samba/2019-July/224365.html Joachim Lindenberg reminded me that he was using smbclient to sync Sysvol. He posted (in the link above) a link to his original post: https://lists.samba.org/archive/samba/2019-July/224346.html Here he posted a copy of his script. I personally would never have thought about using smbclient, but it just goes to

Since compiling R 2.5.0 from source on my Mac (PowerBook) I've noticed some strange behavior when plotting. I'm not sure if it's a problem with my setup/compilation because I feel like a problem as basic as this one would have been reported already. I'm running R with X11 and R was built with gcc 4.0.1. Basically, I run > plot(0, 0) > dev.off() X11 4 Warning message:

I'd like to remove automatically a directory that may be non empty. I tried: > file.remove(NewDir, recursive=TRUE) [1] FALSE Warning message: In file.remove(NewDir, recursive = TRUE) : cannot remove file 'Prostate_Validated_mirWalk', reason 'Directory not empty' Is there another command to remove entire directories including their contents ? Thank you. Maura tutti i
