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 suggestions? Thanks i...

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

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 Halvorsen

...the registration once the other package has done so. But my namespace is locked by the time this occurs. Can someone either tell me how to do this, suggest a better alternative, or point me to another package that does something similar?

...slow connection between the machine running R and the X server. The additional software might not work correctly.

Hi folks, I note that in the general FAQ's we have 7.25 Why did my .Rprofile stop working when I updated R? Did you read the NEWS file? For functions that are not in the base package you need to specify the correct package namespace, since the code will be run before the packages are loaded. E.g., ps.options(horizontal = FALSE) help.start() needs to be

I'm using Suse Linux Enterprise Desktop 10.2 (SP2) on an HP 2133 (x86) mini-notebook. (There apparently are a LOT of bugs in 10.1!) I downloaded R-base from the openSuse 10.2 repository and was (finally) able to install it (after installing blas and gcc-fortran). I can start an R session and do computations. When I try to do any graphics using x11, I get the message: unable to load shared

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 =
