Hi all I wish to create a ps file of a picture produced in R. With my limited R, I see two ways: 1. Print direct to the postscript device 2. Print to the screen, and save to ps using dev.print. I want a white (not transparent) background. Option 1 above works fine, but 2 does not: even when I say I want a white background, I get transparent; perhaps I misread the help files. Here's some R

Hi all I'm using Sweave and find it a treat. But one question: I use Sweave to create my pictures which are automatically included into LaTeX. For example, in the file test.Snw, I may have: % LaTeX stuff \begin{figure} <<fig=true,width=5,height=5>>= x1 <- seq(1,5, length=10) x2 <- sin(x1) plot(x1,x2) @ \caption{Plot} \end{figure} % More LaTeX This produces the LaTeX

Hi all I am doing some stats work for a group of biologists who require windows metafiles (*.wmf) for their publications. To create these, I appear to have two choices: 1. Restart my machine in Windows and use savePlot 2. Keep my machine in linux, save as another format, then convert. I'd rather stay in linux; but how do I get wmf files? I looked at using ImageMagick's convert,

Hi all I am using R to produce postscript pictures via the postscript command. I have never had any problems... until now, when I want to inlcude my .ps file is a LaTeX document *without* a white background. (If it's important, I'm using the prosper class with the whitecross option, so the background in blue.) I would like my .ps file to have a white background. If I read the help

Hi all I posted a couple of days ago about how to end up with wmf files eventually in R for linux. The short answer was: you (probably) can't...and don't! The journal in question also accepts TIFF files, I am told (it's a physiology journal). So I adjust my question: What is the best way to get TIFF files out of R? It can't create them directly as far as I can tell.

Hi all I have a question about plotting line types and legends. Here's a short piece of code to demonstrate: x <- y <- seq(1,10) plot(x,y, type ="l", lty="33") lines(x,y+1, lty=1) legend( 8,2,legend=c("lty=1","lty=\"33\""), lty=c(1,"33") ) On my system (see below), the line types in the legend are not the same as in the

Hi all I'm getting a NaN returned on using dffits, as explained below. To me, there seems no obvious (or non-obvious reason for that matter) reason why a NaN appears. Before I start digging further, can anyone see why dffits might be failing? Is there a problem with the data? Consider: # Load data dep <-

Hi all I am trying to package a library in R 1.6.1 (Windoze XP). I have read the document "Writing R extensions" and think I have done things correctly (though apparently not). I have searched the mail archives for help to no avail. I also posted a few days ago and thanks to Peter Dalgaard I have managed to focus my search for errors. I am trying to create a library in R. I run the

Hi all Suppose I do the following: set.seed(1000) library(xtable) x <- runif( 10 ) y <- 1 + 2*x + rnorm( length(x) ) test.lm <- lm( y ~ x ) summary( test.lm ) xtable ( summary( test.lm ) ) The final xtable output follows: % latex table generated in R 1.8.1 by xtable 1.2-2 package % Tue Jun 22 09:56:36 2004 \begin{table}[ht] \begin{center} \begin{tabular}{rrrrr} \hline &

Hi all, I am trying to package a library in R 1.6.1 (Windoze XP). I have read the document "Writing R extensions" and think I have done things correctly (though apparently not). I have searched the mail archives for help to no avail. When I try to attach the library using, eg > library( libname, lib.loc=path.to.library) I get this message: Warning message: NAs introduced by

Hi all I am converting an S-Plus function into R. The S-Plus code uses some of the glm families, and family objects. The family objects in S-Plus and R have many different features, for example: In R: > names(Gamma()) [1] "family" "link" "linkfun" "linkinv" "variance" [6] "dev.resids" "aic"

Hi all I have a plot with lines, one specified as (say) lty=1, using standard line types, and another as (say) my own spec: lty="51". I can't get legend to display both. Toy example: > plot(1~1) > legend("topright", lty=c("51",1), legend=c("My own","Standard")) Error in segments(x1, y1, x2, y2, ...) : invalid line type: must be

Hi all I am having troubles making sense of why code (1) below fails but code (2) below works. Code (1): > phi.1 <- 1 > plot(0 ~ 0, + main=substitute(paste("A vaue for ",phi," = ",phival), list(phival=phi.1)) ) Error in paste("The two deviances for ", phi, " = ", 2) : Object "phi" not found But this works: Code (2): >

Hi all I'm doing some things with a colleague comparing different sorts of models. My colleague has fitted a number of glms in Genstat (which I have never used), while the glm I have been using is only available for R. He has a spreadsheet of fitted means from each of his models obtained from using the Genstat "predict" function. For example, suppose we fit the model of the type

Hi all I'm using Sweave and LaTeX, and love how they interact. But here's a different interaction I'm not sure how to achieve; I hope someone can help. I use a simple example, of course, to demonstrate. Suppose in my LaTeX document I have this: Here is a linear equation: \begin{equation} y = -1 + 3 x \label{EQ:example} \end{equation} This appears in the final product

Hi all After posting what follows, Duncan Murdoch suggested perhaps a bug in formatC, or an error on documentation. Any comments? In particular, bug, error or not, any ideas about how I can consistently get two significant figures to print? P. ---------- Original Message ---------- Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of

I have been attempting to create a custom fax cover sheet for a hylafax web front end called avantfax. It requires as input an encapsulated postscript file conaining the glyph definitions and the text to be subsituted as strings having the form XXXX-to-variable or XXXX-from-variable. I have been trying to create a valid eps file using a varitiy of methods with no great succes. However, I ahve

Hi all In two days, I am giving a small, informal workshop in our Department about using R. Initially, it was just for statistician, but surprisingly (to me anyhow) many mathematicians are also coming who have a MATLAB background. They are coming at the Workshop from a teaching perspective. They are considering using R to avoid licensing issues with MATLAB. One thing they were hoping me to

Hi all I love Sweave; use it all the time. But I recently received a new computer, and ever since I have had a problem I've never seen before. For example, I place the following in my Snw file: <<>>= sms <- read.table("http://www.sci.usq.edu.au/staff/dunn/Datasets/applications/popular/smsspeed.dat", header=TRUE) attach(sms) sms.lm <- lm( Time ~ Age*Phone,
