similar to: how to trap any warnings from an R function

With the incorporation of the useful hints, my user function now looks like this: userfn <- function() { ... ow <- options("warn") options(warn = 2); ... reg<-try(polr(act~.,data=mm,Hess=TRUE)) ... sumreg<-try(summary(reg)) print(length(sumreg)) print(sumreg) ... options(ow) # reset } The routine userfn() is called multiple times, two of which I happen to know to

Dear R experts: I am running some calculations using polr() in MASS library, and found some differences in results obtained on two different machines (IRIX 6.5, and Linux RH 7.1). It is not clear to me whether this is due to some error in my programming the calculation and how to resolve the differences, if possible. The polr() call is the following:

I am running a windows executable, using wine, in a 'batch mode' - ie multiple times with different command parameters to the executable. For some parameters, the 'Program Error' dialog box appears and the wine process does not continue until the dialog box is closed. Is it possible to suppress the dialog box such that the entire batch can be completed without intervention?

I have used plor() to model a rather large 3-category dataset (~1500 data points, ~15 independent variables); from the resulting model (with a deviance slightly below the residual degrees of freedom), the training data are placed in only the two extreme categories. Though the result appears to indicate that there's only a relative 'narrow' bin for the medium group, [and when the

Sorry for the off-topic question, but I know there are some talented LaTeX users out there. Which bibliography style gives only the year in text citations (e.g "for further details, see Anderson (1992)" )?

Dear all, Our department uses the linux system and we are not allowed to submit job directly. We must make a batch to submit through "qmon". so, I make a foo.sh file, which only contains one line: nohup R --vanilla < foo.txt > foo.results foo is all my codes. It is a simulation of 200 times. I set the seed at the beginning. It is to estimate the success probability, which is

Hi, I found that the R package "KernSmooth" can deal with only 1D and 2D data. But now I have a collection of 4-dimensional data (x1,x2,x3,x4) and would like to estimate the "mode" of the underlying density. What can I do about it ?

I think that there is a bug in the as.POSIXct function on Windows. Here is what I get on Win2000, Pentium III machine in R 1.8.1. > dd1 <- ISOdatetime(2003, 10, 26, 0, 59, 59) > dd2 <- ISOdatetime(2003, 10, 26, 1, 0, 0) > dd2 - dd1 Time difference of 1.000278 hours Now, the 26th of October was the day that change to the standard time occurred, so I suspect that this has

For R-1.4.0, I have been able to build R.bin with -O2 flag. This however did not yield any significant speed-up for my code. I then tried building the binary for 64 bit, but had not been able to configure the build; none of the suggestions that I can find in the r-help search worked for me. I'm looking for any other suggestions -- TIA mod:>> uname -a IRIX64 mod 6.5 10100655 IP35

Not having paid any attention, I discovered that this file grew to be 1048518656 bytes (this on a debian-based Linux system), and filled up the (small) filesystem for /var. Is there a 'normal' size that I should expect for this file ? What could be the reason for the large size? And how could it be best reduced? (There was a suggestion of stopping samba, removing the file, and

I'm running polr() and getting warning messages from glm.fit(). It seems reasonable to use glm.control() to turn on the trace and follow what glm.fit() does when called by polr(); or is it? glm.control(maxit=10, trace=TRUE) polr(act~., data=mm) The glm.control() sets the trace TRUE, but there's no change in the output from polr(). Many thanks in advance for any help/pointers.

Are there more detailed documentations for writing fortran routines than "doc/manual/R-exts.html", or some examples of such routines available?

Dear List: I am unsure if my problem is with Sweave or LaTeX. Anyhow, I am using the MikTeX distribution and TexnicCenter. I can easily create Sweave files and all goes well until I try to incorporate graphics. I use the same code as found in the examples found in the users manual. In R, the graphics I want are created as Sweave is creating the .tex file. When I examine the .tex file

Having trouble with netCDF since I upgraded to 1.2.1 (did directly from 1.1.1). Package was recompiled after the upgrade. Symptoms: open.netCDF returns cleanly, but read.netCDF causes R to segfault and dump core.

OK. What if I have a time series which is collected every Monday, please? What is the proper way to use the start option within the ts command in order to indicate that this is Monday data, please? Thanks again! Sincerely, Erin

Hi, I am trying to use piecewise linear regression to approximate a nonlinear function. Actually, I don't know how many linear functions I need, therefore, I want build an array of regression models to automate the approximation job. Could you please give me any clue?

Dear R experts, I installed R-1.7.1 on Linux (Red Hat 9.0) starting from R-1.7.1.tgz without a problem. Then I fired up R and tried things and found that help.start( ) does not work. I downloaded Sun Java j2re1.4.2, installed that and re-installed R-1.7.1 from scratch. I tried help.start( ) again and the browser (Mozilla 1.2.1) crashed. I read about copying libjavaplugin_oji.so into
