Hi, I am trying to find a way to automate production of page numbers in plots produced using the lattice package. To do this, I started playing around with setHook which works fine with vanilla plot, but the hook 'plot.new' doesn't appear to be relevant to the lattice package. I was wondering if there is a alternative someone can suggest for use with the lattice package. Example code: library(lattice) graphics.off() myFunc <- function() {...

Hi, is there away to assure that a package is detached when R quits? I know about .Last(), but that requires the user to setup that function. What I am looking for is a way for the package to do this itself, without asking the user to edit "their" .Last(). From ?setHook I know that: "...when an R is finished, packages are not detached and namespaces are not unloaded, so the corresponding hooks will not be run." I am going to use this to load settings from file when a package loads and automatically save (by optionally prompting the user) them back...

Thanks a lot. setHook is Currently not in my knowledge set But it's great to save these Thing so I can look them up When I feel more comfortable. Just to add to that Stata versus R discussion : I believe, anyone who uses any other package than R, is probably missing out in the long run. It's truly unbelievabl...

Dear List, I've tried to set default par() in .Rprofile by putting the following in the .First function: setHook(packageEvent("graphics", "onLoad"), function(...) {graphics::par(cex.axis=1.5, cex.lab=2, las=1)} ) My goal was to set par() defaults without opening a device everytime at startup. However, the next plot I create doesn't show these defaults. Any suggesti...

Hi all, several packages print messages during loading. How do I avoid to see them when the packages are in the defaultPackages? Here is an example. With this in ~/.Rprofile ,----[ ~/.Rprofile ] | old <- getOption("defaultPackages") | options(defaultPackages = c(old, "filehash")) | rm(old) `---- I get as last line when starting R: ,---- | filehash: Simple key-value

Dear R experts, I just upgraded R from 1.8.1 to 1.9.0 version. My .First() function in ~/.Rprofile contains x11() and par() functions. .First <- function() { x11(display = "", 8.0, 5.0) par(las = 1, ...) ## ... } And, R claims now, on startup: [hello messages skiped ...] Error in .First() : couldn't find function "x11" > I commented

Hi, Is there a way to incorporate an R object x to a file already containing R objects? It seems that 'save' is not capable to do this. If I save x to a file containing previously saved data, then I will lose this data. I use the funcion hsv in .Rprofile but it is recognized. Couriously, if I source .Rprofile when R is already running I do not get any error message. Thank you.

I think I did enough reading on my Own about startup ( part of the morning And most of this afternoon ) to not feel uncomfortable asking for confirmation of my understanding of this startup stuff. Obviously, the startup process is more complicated Than below but, for my R newbie purposes, It seems like I can think of the startup process as follows : Suppose my home directory =

Hola! There is a nuisance that the number of directories with name starting Rtmp (and always empty) in my temp directory is increasing over time. I put the following in my .Rprofile: tmp0001 <- tempdir() setHook( packageEvent("base","onUnload"), function(...) unlink( tmp0001, recursive=TRUE) ) which solves part of the problem, but not all. So there are also other tmpdirs made by R. Why, where, and why are they not removed at exit (when their content are removed)? Kjetil Halv...

...iro_png draws the box even when par(bty="n"). I just tested this on Debian with version 2.6 of cairoDevice. I've also observed this behavior on Windows and it's not a new problem. The only workaround I've found is to call > Cairo_png() > par(col="white") > setHook("plot.new", function() par(col="black")) > plot(...) As far as I'm concerned, this is a serious bug, it's a real problem when creating figures for publication. I'd like confirmation that this is, in fact, a bug as I haven't seen much documentation for standar...

Hi all, Today, i just installed the newest R version 2.10.1 and other necessary tools for building R package under windows,e.g. Rtools, perl. All are the newest version. After the correct configuration under windows, i use it to re-check my old package. I found the following prolem when checking EXAMPLE, which did not exist before this re-installation. ######## * checking examples ... ERROR

Can someone either tell me how to do this, suggest a better alternative, or point me to another package that does something similar? Current attempt is something like the following: setHook(packageEvent("somepkg", "attach"), function(...) { cat("* Register", sQuote("oldstyle"), "as S3 class", "\n") setOldClass(c("oldstyle", "data.frame"),...

Dear all I installed new version (from binaries) and I noticed that par(bg="white") which I have in my .Rprofile causes error message on startup But if I issued this command immediately after startup everything worked as expected. I did not see any note in changes file or elsewhere. Should I specify white background in .Rprofile differently? Or is there some other recommended way

After upgrading to R 1.9.0, I started getting the following error on startup: Error: couldn't find function "ps.options" My .Rprofile file contains this line: ps.options(paper="letter",horizontal=F) If I type "source ~/.Rprofile" after R starts, it works just fine. Did something related to startup change in R 1.9.0? -akop
