Is there a limit on the number of pages that can be in a pdf file? I am using pdf() (on R version 1.4.1, running on Red Hat 7.1 on an Intel box) to create a large (> 300 pages) file of diagnostic plots. If I plot every figure I want to include (364 pages, according to Acroread ver. 5.0.5), neither xpdf on Linux nor Acroread ver 5.0.5 on Win98 can render the file. xpdf give the error message:

This is in Windows 98. The problem exists in both rw1021 and rw1023, using ActiveState Perl builds 620 and 626: C:\>Rcmd REMOVE --library=C:/R/Rlibs RBMDS Unknown option: library Usage: Rcmd REMOVE [options] pkgs Remove the add-on packages specified by pkgs from the default library tree (/library) or the tree specified via `--library'. Options: -l, --library=LIB remove packages

When I execute the following code: bitmap("test.pdf",type="pdfwrite") plot(1:10,1:10,main="ONE") plot(1:10,1:10,main="TWO") dev.off() the resulting file test.pdf contains four pages: graph ONE, graph TWO, graph ONE, graph TWO. I can recreate the problem with R version 1.2.1 and 1.2.2. I am using Aladdin ghostscript version 6.50. The temporary file

This is not a request for help, but I thought the readers of this mailing list might appreciate the following, anyway. I have been working with US EPA's (that's the United States Environmental Protection Agency) Office of Pesticides on a preliminary assessment for the effects of exposure to multiple organophosphate pesticides on human health (as required by the Food Quality Protection

I KNEW I shouldn't trust my memory; the pdf() help page documents a page limit of 500; I don't seem to be exceeding this, however. R. Woodrow Setzer, Jr. Phone: (919) 541-0128 Experimental Toxicology Division Fax: (919) 541-5394 Pharmacokinetics Branch NHEERL MD-74; US EPA; RTP, NC 27711

Does SJava require that omegahat be installed? I have installed the binary Windows package (SJavaWin_0.62-8.zip), made the change eliminating the call to .alias(), with the following results on startup: > library(SJava) > .JavaInit() Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find the Omegahat interface manager class. Check you classpath! > tmp <-

I am having trouble getting smooth-appearing curves in figures produced as windows metafiles using R (R-1.1.1 on Windows 98). When I import them into a word processor (either MS Word 97, or WordPerfect 9.0), the figures appear only slightly bumpy on screen, but when printed, there is a clear jaggedness reminiscent of aliasing. Is there a fix for this (if the answer is "upgrade to 1.2",

I first noticed this in gnls, but it also happens in lm, so I suspect the following phenomenon is universal in modeling functions. Modify the example from the lm help: model <- as.formula(weight ~ group) lm(model) The result will be printed: > lm(model) Call: lm(formula = model) ^^^^^^^^^^^^^^^^^ Coefficients: (Intercept) groupTrt 5.032 -0.371 This is because in lm,

I just noticed this behavior of plot(). If you combine: log="y", with type ="s", specify ylim, AND have plotting points outside of ylim, then the R process hangs. For example: plot(1:10,seq(0.0001,1,length=10),ylim=c(0.01,1),type="s",log="y") It will also hang if the original plot() command did not specify ylim, but a subsequent

If a function needs to be passed as an argument to another function, default arguments to the function being passed are lost. Consider this example: fun1 <- function(x, A=c("power","constant")) { arg <- match.arg(A) cat(paste("A is:",paste(A,collapse=", "),"\narg is:",arg,"\n")) cat("formals:\n") print(formals())

I think this is a bug; at least this behavior is not documented in plot or plot.default. plot.default resets xaxp, and leaves xaxp reset when it exits: par(xaxp=c(0,1,4)) print(par("xaxp")) plot(c(0,1),c(0.2,0.3)) print(par("xaxp")) R.

I'm getting an error from nlme that has me stymied. I have a data set ,'mydata', with variables: AChE, Dose, sex, set, and mrid; 'set' and 'mrid' indicate two levels of nesting, with 'set' nested within 'mrid'. I want to fit the model: mod <- nlme(AChE ~ Cexp(Dose, A, B, m), data=mydata, fixed = A+B+M~sex, random=A+B+m~sex | mrid/set,

I have a package that solves systems of ordinary differential equations coded as an R function (odesolve, on CRAN). The function is passed to R code, and c and Fortran code called by it uses lang4() and eval() to evaluate the R function inside a compiled c function to use in a compiled ODE solver. This works quite well, but can be slow. I'd like to be able to supply the name of a compiled

Probably I've just misread the documentation, but I don't understand the behavior of .Alias. Consider this (on R-1.1.1, both Windows and SGI): > tmp <- matrix(nrow=3,ncol=2) > new <- .Alias(tmp) > new[1,1] <- 1 > tmp [,1] [,2] [1,] NA NA [2,] NA NA [3,] NA NA > new [,1] [,2] [1,] 1 NA [2,] NA NA [3,] NA NA I expected tmp[1,1] to

I've written an application that uses the tcltk package, and have distributed it to a few people to use here in the Agency on Windows 98 machines. It has worked just fine on all but one of those machines. On that one (system information quoted below), we persist in getting the error message: > require (tcltk) Loading required package: tcltk Error in dyn.load(x, as.logical(local),

When I try to open a server socket on the system setup listed below, I get the following error: > a <- make.socket(port=8091,server=TRUE) Error in make.socket(port = 8091, server = TRUE) : sockets are not available on this system I just wanted to make sure that sockets were generally available for this platform (or, perhaps, I need to upgrade to 1.2.2 on this system), before I got

I would like to be able, inside a function, to create a new function, and use it as part of a formula as an argument to, say, gnls or nlme. for example: MyTop <- function(data=dta) { Cexp <- function(dose,A,B,m){...} Model <- as.formula(paste("y","~ Cexp(",paste(formals(Cexp),collapse =", "),")")) MyCall <-

I think qqline does not do exactly what it is advertised to do ("`qqline' adds a line to a normal quantile-quantile plot which passes through the first and third quartiles."). Consider the graph: tmp <- qnorm(ppoints(10)) qqnorm(tmp) qqline(tmp) The line (which I expected go through all the points), has a slightly shallower slope than does the points plotted by qqnorm. I think
