Dear Colleagues, I've recently upgraded to SUSE-LINUX 9.0 and R 1.8.1 (using the RPM-'s from CRAN). I've checked that all required LINUX-Packages as listet in the README.html in /bin/linux/SUSE are installed. I've then tried to INSTALL and check a package. Installation with R CMD INSTALL -l Rcontrib aws * Installing *source* package 'aws' ... ** libs make:

Full_Name: Jörg Polzehl Version: 1.8.0 OS: Windows XP Submission from: (NULL) (62.141.176.1) I encountered a problem when playing with the mle library and specifying negative starting values for the parameters. The reason seems to be an incorrect behaviour of function formals: glike<-function(a=1,b=1,c=1) a > formals(glike) $a [1] 1 $b [1] 1 $c [1] 1 > unlist(formals(glike)) a b c

Hi all, I've noticed that many computational neuroscience research groups use MATLAB. While it's possible that MATLAB may have some features unavailable in R, I suspect that this may instead simply be a case of costly tradition, where researchers were taught MATLAB as students and pay for it as researchers because it's all they know. I'd like to attempt to break the cycle by

many thanks to P. Dalgaard, J. Fox, J. Lemon, JE. Paradis and J. Polzehl for their quick replies. The original posting is at the end of this summary. I've not well explained myself but I don't wanted to use par(mfrow) or par(mfcol) because I wanted to plot very different graphics and this solution doesn't match my needs. E. Paradis and P. Dalgaard made me discover a new (for me!)

hi list- Under windows 2000 I was asking for more than the 256MB limit. solutions (and first suggester) were: 1) Reading the rw-FAQ and ?Memory for memory management under 1.2.x. (Prof Brian Ripley) <- this is the one I should have used 2) Run with P:\r\base\rw1022\bin\rgui.exe (Thomas Lumley) <-this is one I used 3) use gc() (Joerg Polzehl) <this is handy Thanx to the list

i want to plot values with frequency on a logarithmic x axis. similar to this example that i found in the web: http://www.usspeaker.com/jensen%20p15n-graph.gif I would like to convert long numbers to si prefix notation like in the example (200000 to 200k, 35000000 to 3.5 M) Of course i could create labels by hand, but i have many files so i need some automatic function. Has anyone done that

Note that this may be neither complete nor perfectly correct at any given instance: Not all bugs are reported, and some reported bugs may have been fixed, but the repository not yet updated. Some bug fixes are difficult to verify because they pertain to specific hardware or

I have a Master's student working on a project which involves estimating parameters of a certain model via maximum likelihood, with the maximization being done via optim(). A phenomenon has occurred which I am at a loss to explain. If we use certain pairs of starting values for optim(), it simply returns those values as the ``optimal'' values, although they are definitely not
