RGUI crash when opening script in XP Home enviroment
If there is a helpfile open (f.e ?glm) and it is the top window, then an exception error occurs (closing RGUI) when I hit the open file button.

Glm
Hi, Is there any way to estimate a DEPENDENT variable through a GLM/LM model? Suppose I have the linear model: y=a0+a1*x1+a2*x2 (a0=1, a1=0.6, a2=0.8, x1~N(1,1), x2~N(0,1)). The alphas and the auxiliary variables are given and I have to estimate y. The point is if I estimate it, let¹s say algebraically, I get high variances that do not decrease as sample sizes increases... Is the any other way

So I have table with Species, Induced defence (ID), and constitutive defence (CD). Since Induced and constitutive defence are not independant (so called spurious correlation) I should do a randomisation test. I have a syntax of my

High resolution plots
Is there any possibility to get high resolution plots in a windows xp system? I tried it with the device function png(filename = "c:/r/highresplot%d.png",pointsize=12, res=900) but when I try to set: width = 480, height = 480 or pointsize = 12, the text is not scaled in the same way as the plots. with regards Knut Krueger http://www.biostatistic.de

texture in barplots?
Dear R list, For some reason I am unable to access neither search.r-project.org, nor http://finzi.psych.upenn.edu/ so I cannot search the archives for a possible answer (I Googled for this but didn't find anything). Is it possible to draw barplots using a texture instead of colors, for a black and white printer? TIA, Adrian -- Adrian Dusa Arhiva Romana de Date Sociale Bd. Schitu

8 char labels in read.spss
I was wondering why it is possible to read long labels from the CVS files but not from the SPSS files. I did not have much time to search for the code but I found: in foreign_0.8-10 source file var.h.in > /* Definition of the max length of a short string value, generally > eight characters. */ > #define MAX_SHORT_STRING ((SIZEOF_DOUBLE)>=8 ? ((SIZEOF_DOUBLE)+1)/2*2 > : 8)
