The beautiful math plot
Dear R-help, How can I replicate the beautiful math plot found in the right-hand side of http://www.r-project.org/screenshots/desktop.jpg? I tried the following code but didn't obtain something as beautiful. r <- seq(-10, 10, len=100) y <- cos(r^2)*exp(-r/6) par(pty="s") plot(r,y,type="l") Thanks in advance!

Security issue
Hello, I am trying to convince our IT Manager that R is as safe as possible from IT security point of view - could you point me to something on the web / some reasons for why this is true? I do not think he has a specific concern but does not know the software and would like to understand the security implications. Thanks in advance Best Regards Martin Hanek Actuarial Analyst Glacier

Fitting models in a loop
If I want to display a few polynomial regression fits I can do something like for (i in 1:6) { mod <- lm(y ~ poly(x,i)) print(summary(mod)) } Suppose that I don't want to over-write the fitted model objects, though. How do I create a list of blank fitted model objects for later use in a loop? Murray Jorgensen -- Dr Murray Jorgensen

New R mailing list: R-SIG-insurance
Dear useRs, Over the last few years R has gained a significant momentum in the insurance industry. Dedicated packages have been written, numerous presentations given, courses held, businesses set up, and IT departments convinced. ;-) Therefore, together with Markus Gesmann of Lloyd's of London, we created a Special Interest Group mailing list to discuss R usage in actuarial science, insurance (life and non-life) and risk analysis and assessment in general. (With thanks to Diego Mazzeo for the idea and to Martin Maechler for the technical help and list cre...

about overdispersed poisson model
Dear R users I have been looking for functions that can deal with overdispersed poisson models. According to actuarial literature (England & Verall, Stochastic Claims Reserving in General Insurance , Institute of Actiuaries 2002) this can be handled through the use of quasi likelihoods instead of normal likelihoods. However, we see them frequently in this type of data, and we would like to

trim function in R
Hi all, I am looking for a function in R to trim the last two characters of an 8 character string in a vector. For example, I have the codes 37-079-2, 370079-3,37-079-8 and want to trim them to 37-079 by removing the last two characters. Is sub the correct function to use, and if so how can I specify trimming the last 2 characters? I have read the help file, but can't quite figure out how

Switching the order of legend boxes in a lattice bar graph
I suspect there is a simple solution to this problem, but have been unable to find it. Below is some code that I have run to create 3 lattice graphs. I have been asked to change the legend so that the 'No' and dark blue are above "Y" and light blue in the legend to mirror the stacked bars in the graph which feature dark blue above light blue. I have tried changing the data

Editor for Mac OSX
Dear R-list I am (forced) to change from Linux to Mac and am now looking for a new editor for R. I would like one that features a split window (console + editor) as well as syntax highlighting. Can anyone help? Especially the split-window feature does not seem to be easily available in the editors desribed on the R-help site, except Emacs, which I am reluctant to start using. I am on a MacBook Air
