similar to: model fitting using by(): how to get fitted values?

Hi! I would like to suggest to make it possible, in one way or another, to get meaningful contrast names when using contr.sum(). Currently, when using contr.treatment(), one gets factor levels as contrast names; but when using contr.sum(), contrasts are merely numbered, which is not practical and can lead to mistakes (see code at the end of this message). This issue was discussed quickly in 2005

Hi, I'm plotting a bar chart like this: ggplot() + geom_bar(data=res,aes(fill=f1,x=f2,y=y),stat="identity",position="dodge") f1 contains quite a few levels and the plot is really quite difficult to read when the order of bars on the graph and on the legend does not match. This problem has been discussed recently here:

Hi everyone, I've got quite a few labels along the x axis and ggplot2 basically just crams them on top of each other. Is it possible to reduce the font size and/or text direction? Stretching the "windows" device window manually also helps, but I found that setting the parameters for the pdf device (where my scripts should print the data), such as paper="a4r" just results

Dear List, I have the following data: >> test <- data.frame(date = as.Date(c('2007-01-01','2008-03-24','2003-03-02','2008-05-03','2002-05-23','2001-06-30','2005-12-04')), nr = c(2000,2000,2000,2001,2002,2003,2003)) test date nr 1 2007-01-01 2000 2 2008-03-24 2000 3 2003-03-02 2000 4 2008-05-03 2001 5 2002-05-23 2002 6

Hi all, I prepared a few charts with ggplot2, and was happy with the results as displayed on screen. I tried to draw them with a PNG driver instead. But I ran into several problems while trying to increase the resolution of the picture. Mainly, when I increased the picture size (e.g png(width=1024, height=768) ), the texts (title, labels, etc...) where too small. I tried to set the

Hello all, I am using Samba on a Debian GNU/Linux box. I am trying to create a netlogon.bat file that will execute whenever a user logs in to the domain. However, I am getting a strange error message on the client workstations. The following is the netlogon.bat: echo Setting Current Time... net time \\xavier /set /yes echo Mapping Network Drives to Samba Server Xavier... net use Z:

I updated wine to latest git (wine-1.1.26-390-g31dab8f) and upgraded my nvidia drivers to 190.18. When I attempted to test some of the DX9 and 10 games I usually test, none of them seem to be able to recognize either my DX version or the drivers. I suspect that the drivers are the issue. Here is a relevant example from a test for Assassins Creed. xavier at xavier-pc

I have completed a binomial GLM in R (details attached (finalModel.docx)) and I am trying to create a graph of observed and fitted values using the following commands: > MyData<-data.frame(time=seq(from=0,to=1323,by=1)) > Pred<-predict(M2,newdata=MyData,type="response") > plot(x=turtle$time,y=turtle$success) > lines(MyData$time,Pred) However, I get the following

Hi Marek Thanks a lot for your rebasing work. Here is my report : - all my games that broke with temporaries patch (they were either completely black or lot of black screen flash every frame) behave badly, but in different ways : * etracer is very slow and often crash in ttm code [1] (I think this is an old bug that just resurrected, no idea why) * foobillard is very slow and still flash a bit *

Dear colleagues, How can I do to "relevel" the intercept? I need that the treatment "Db" be the intercept, and have p-values for the comparisons with the others treatments. I used the function "relevel" but it did not work out to have what I want. Thanks for your help, Xavier T1 <- read.table(file.choose(), h=T) > head(T1) treatment replicate Time

The current CVS Project Shorewall2/ contains my implementation of this feature. Thanks go to Xavier for ideas about the design.

Oh, I completely missed that one. It's very neat as it seems to work both on Windows and Unix. Thanks!

Native dinput8 and d3dx9_36 have to be used in order for the game to load and workaround mouse input (see http://bugs.winehq.org/show_bug.cgi?id=16822). When I start a new game, after setting up Shepard's profile and waiting for the first cinematic to play there is an ntdll error which freezes the game. Any clue on how to workaround it?

Hello! I work with: R : Copyright 2006, The R Foundation for Statistical Computing Version 2.3.1 (2006-06-01) On Windows XP Professional (Version 2002) SP2 I think there is a bug in the conditional execution if (expr1) {expr2} else {expr3} If I try: "if (expr1) expr2 else expr3" it works well but when I put the expression expr2 and expr3 between {} I receive an error message
