Hi All, This question was brought up some time ago but I never saw a reply so I'd like to bring it up again. When using ROracle package (version 0.5-5), I am unable to run any queries that are greater than 4000 characters in length. If I do, I get the following message: Error in oraPrepareStatement(con, statement, bind=NULL) : RS-DBI driver: (too long a statement -- it must has less than

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 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 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 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 Two questions: 1. I note that help for the postscript device claims "The postscript produced by R is EPS (Encapsulated PostScript) compatible...". It does not say it is EPS *compliant*. Indeed, the EPS produced by R includes a \showpage command which I believe (not that I'm an expert!) non-standard EPS. My question: Is there any reason why it is EPS compatible, but

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 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 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 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 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 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 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 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

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 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,

Hi all I'm updating a package for submission to CRAN, and I am getting an error message I never have seen before, and can't find out what it implies or means (and hence, what I need to do to fix it).

Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of reals to a given number of significant digits. Can someone please explain this to me? These first three give what I expect on reading ?formatC: > formatC(0.0059999, digits=2,format="fg",flag="#") [1] "0.0060" > formatC(0.59999,

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
