Just wanted to alert everyone regarding a problem that I only experience with R2.9.0 and not with R2.8.1 when I run both using exactly the same script and the same data. Here is what I do with my data "MyData", 2 predictors (V1 and V2) and my survival DV "Depvar": library(survival)

survival:: plotting survfit with two predictors
Hi R-Helpers, I am having difficulty plotting a coxph model with two predictors. My predictors are "morder" (a factor with five levels where the mean of each level is plotted as a separate line) and tmean (continuous). When I run a model with just morder it is fine and the plot is fine. When I add tmean, the coxph model runs fine but this model will not plot and I receive an

RGui Configuration Editor crashes when using an unlisted font
I am using R2.9.0 under Windows XP SP 2 (32-bit). I just discovered a rather excellent programming font (http://www.dafont.com/bitstream-vera-mono.font). Since it isn't one of the fonts listed as an option in the RGui Configuration Editor, I manually editted my RConsole file font line to font = Bitstream Vera Sans Mono When I opened R, the text in the console displayed correctly, but

scan function
Hi, I'm using R2.8.1 in windows vista and the scan function to load in my data. That works all fine except that I get a message after the scan function finishes. It tells me how many items the function has read. For example "Read 202035 items". That would not be a problem but this is printed in the stderr stream which causes a problem in a different software I run the r scipt in. I

ggplot2: specifying legend titles
I am trying to specify a legend title to be other than the variable name, but I find that the legend splits because scale_shape() takes effect but scale_colour() does not. Can someone spot my error? Here's some toy code that produces the problem on my system (R2.8.1, windows, today's CRAN package updates): library(ggplot2) a <- sample(letters[1:5],100,replace=T) b <-

Rmysql linking to an old-ish mysql build
Hi, I'm trying to get Rmysql to work o windows server 2008 64-bit. I have the latest build of mysql installed (mysql-5.1.34-winx64).

R/octave/matlab etc.
I'd echo a lot of what has been said about this by the folk who have been making R work so well. One of the main difficulties is that the environment of computations affects relative performance. e.g., what settings did a distro package builder choose. I note that my 3 GHz Dual Core machine running Ubuntu 8.04 gets octave 3.0.0 octave:6> tic; a = a + 1; toc Elapsed time is 0.120027
