Does anyone know how to interrupt R in RedHat? Neither control-c nor Esc is working. What I don't want to do is close the window or kill the entire R process. Thanks, David This communication is for use...

Given a numeric vector of observations, does R have any generic way to estimate the parameters of commonly used distributions (exponential, gamma, etc.) without numerically optimizing the likelihood function? Thanks, David _______________________________________ David R. Bickel http://davidbickel.com Research Scientist Pioneer...

Does anyone know how to use the equivalent of debug() on an S4 method? I would like R to enter the browser not for the generic function, but for the method of the class that I specify. Thanks, David _____________________________ David...

R never gave me any serious problems until I tried to use it on Windows XP. I had 1.8.1 installed and working successfully for a few weeks. This morning when I launched it, I received this error message...

Are there any R functions or packages that can compute distributions, expectations, or quantiles of order statistics (or sample quantiles or extreme values) for a given distribution such as a normal distribution? Both exact and asymptotic calculations are of interest...

Is there a function that provides the Fisher information matrix for a generalized linear model? I do not see how to access the off-diagonal matrix elements of the value returned by glm. (I'm particularly interested in logistic regression...

Is there any R function that can display a Postscript file that is already in the working directory? For example, if 'graph.ps' is such a file, I'd like to type something like this: > plot.postscript.file(file = 'graph...

Is there any R function that computes the convolution of the double exponential distribution? If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from 0 to Inf for any value of q and...

Is there a way to call an R function to work in the background within the same R session? What I have in mind is the equivalent of adding '&' at the end of a UNIX command, so that R can...

Is there a way I can have R automatically execute the commands in a source file without ever having to use R interactively? If so, what arguments should I pass to the UNIX call to R? I need to do...

Is there a way I can get R to automatically enter the browser inside a user-defined function on the generation of an error? Specifically, I'm trying to debug this: Error in as.double.default(sapply(lis, FUN)) : (list...

Patrick, control-c seems to interrupt loops, but not the display of enormous objects, as when I typed the name of a several-hundred megabyte list. Is there a way to interrupt that? control-D does not interrupt R, but...

After reading the help page on set.seed, I am unsure about how to solve the following problem. I need to call function f a thousand times. The list of values returned by f, should be as random as possible...

Ravi, Duncan, and Matthias, Thank you very much for the helpful replies. For convolutions with 2 or 3 copies, I found that the CDFs from the distr package closely match the analytic results from this paper: K. Singh, M. Xie...
