Dear List, Below is a simple, standard loss model that takes into account the terms of an insurance policy: deductible <- 15 coverage.limit <- 75 insurance.threshold <- deductible + coverage.limit tmpf <- function() { loss <- rlnorm(rpois(1, 3), 2, 5) sum(ifelse(loss > insurance.threshold, loss - coverage.limit, pmin(loss, deductible))) } net <- replicate(1000000, tmpf())

I would like to be able to randomise presence-absence (i.e. binary) matrices whilst keeping both the row and column totals constant. Is there a function in R that would allow me to do this? I'm working with vegetation presence-absence matrices based on field observations. The matrices are formatted to have sites as rows and species as columns. The presence of a species on a site is

Please help me evaluate a "dynamic variable" as show in the code snippet below. # regular variable a = c(1,2,3,4) # dynamic variable set at runtime DV = "a" eval(DV) --> a eval(eval(DV)) --> a # what I want something_goes_here(DV) --> 1,2,3,4 Can someone teach me how to do this? Thanks very much. - Bobby

I have a question about antialiasing when R generates bitmaps. (This follows a thread on the ggplot2 mailing list.) I mostly use R on Linux, although I sometimes use it in Mac and Windows as well. On Linux, I've found that plotting shapes 15-18 via cairo results in bad-looking output. The points are not antialiased, and they are jagged and misshapen. Plots generated in Windows also aren't

I''m doing a graphics application and need onscreen anti-aliasing for both lines and text. Seems like wxGraphicsContext would do that, is that planned to be ported to wxRuby? Best regards, Jari Williamsson

Is there a way to get Wine to use Render extension in XFree86 4.0.3 to allow it to have antialiased fonts? David

Hi, I installed MS Word 2007 on Debian Lenny using the latest Wine 1.3.20 - everything seems running ok. The only thing that I don't like are the fonts. I enabled with winetricks the font smoothing, but.... Some of them (Times New Roman, Calibri, expecially) still look aliased at given dimensions (12pt and below): increasing their size solves the problem and they become anti-aliased, but this

I've narrowed the my Cups printing problem down to Wine not loading my Type 1 fonts. I have several Type 1 fonts installed in 3 places, all of which are in my fontpath ("xset q" lists them). I can use the Type 1 fonts in X and with KDE-2.2.1 even as AntiAliased, however, when I try to print from an app under wine I get a memory error and a message at the command line stating

OK, back with another iteration of the same problem... I updated my game demo, but the Close button failed to respond when (and only when) there were too many objects onscreen. The drawing loop is probably lasting longer than my drawing timer interval. I was able to reproduce the problem in my (probably familiar by now) test script just by boosting the number of lines drawn per frame. After

Hello, in the tunk, i found a new style for spec: describe Foo do it "should do bar" do ... end end instead of context "Foo" context "should do bar" ... end end The Rails-Textmate-bundle in trunk use only the new "describe-it" style, What are the reasons for the new style ? Shall i use the new style from now on ? Hussein

Hi folks, Debian 504 64-bit Emacs Version 22.1.1 I have Emacs+ESS running on the box. R can work on ESS. But the fonts on the menu bar (top) of Emacs are NOT clear, difficult to read, grey foreground. I have been googling around for solution without result. Please help. TIA B.R. Stephen L

The announcement for Wine 1.1.12 says that support for subpixel font rendering has been added. The question is, how can we use it? Is there a way to enable it globally (there's no such setting in winecfg).

Good afternoon from Singapore, May I know roughly how many more months before CentOS 8.0 will be released? https://wiki.centos.org/About/Building_8 Thank you very much. -----BEGIN EMAIL SIGNATURE----- The Gospel for all Targeted Individuals (TIs): [The New York Times] Microwave Weapons Are Prime Suspect in Ills of U.S. Embassy Workers Link:

Does wxRuby support font antialiasing on Linux or does it depend on the underlying toolkit? If not, are there plans to include it? If I use wxGTK, is antialiasing automatically enabled? Do I have to do something to make my fonts antialiased? Bill

I'm trying to build and check a new package. But keep getting the warning: * checking PDF version of manual ... WARNING LaTeX errors when creating PDF version. This typically indicates Rd problems. When I go into the package.Rcheck directory, package-manual.pdf is created. however if I do a pdflatex on package.tex I get the following: This is pdfTeX, Version 3.1415926-2.4-1.40.13

So Wine's main problem right off the bat, the big elephant in the room nobody really talks much about, is that its *apperance and performance in 2D apps is abysmal. It's odd, because 3D apps (after a small framerate drop) perform just fine. Maybe there's some technical explanation as to why 2D applications feel so sluggish by comparison, but that's not what I'm here to discuss.

Given the data structure below and the call to ggplot2, how can I increase the size of the axis scale points, the line weight, and the size of the legend? ddata <-structure(list(year = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("2003", "2007"), class = "factor"), area = structure(c(7L, 6L, 1L, 2L, 3L, 4L, 5L, 7L, 6L, 1L,
