similar to: MakeActiveBinding help needed

A while ago Luke Tierney remarked that the warning associated with 'makeActiveBinding'-- "saved workspaces with active bindings may not work properly when loaded into older versions of R"-- should probably be removed in R-devel. It's still cropping up *sporadically* with R-alpha of 3/4/2004, but not every time I call 'makeActiveBinding'. So, two questions: (i) is it

I've seen a number of issues with the loading of workspaces discussed previously, but here's another one... I simply can't load any saved workspace at all... Here's an example, starting with an empty workspace and creating a single variable "a". > a<-1:5 > save.image("a.Rdata") > rm(a) > load("a.Rdata") Error in function ()  : unused

Plaintive squeak: Why the change? Some OS's and desktops use the extension, so forgetting it causes trouble. The new default filename keeps a filetype (as before) but the user now has to type a filetype twice (once as the type, once as extension) to get the same effect fo rtheir own filenames. And the extension isn't then checked for consistency with valid file types, so it can be

Hello, I am unable to start an R session by double-clicking on an existing .RData file from the Windoze file explorer. A dialogue appears with the message "Fatal error: unable to restore saved data in .RData", and I notice in the R Console the last few lines are: "Loading required package: R2HTML NULL error in function () : unused argument(s) (1:43)" I tried starting

Hi all, After a short hiatus away from R I have found that it's changed a bit. I used to keep a definition of .First in .Rprofile that did a couple of things on startup (load a couple of libraries). Now, I've discovered that when I change the definition of .First in .Rprofile it doesn't change anything when I start up, because .First is held over in .Rdata from the last session.

I use the ugly hack shown below as my .Rprofile (mainly because I couldn't find any other way to spawn a new mozilla window on starting R or calling help.start(), but then send all the help html documents to that new window). With a recent change from a cvs checkout to the released 1.9.0 I find that the new hs() appears if there is nothing of that name in .RData, but if there is the old hs()

NOTE: WinXP, R2.2.0 All, a while back I posted a question about using relative filereferencing. The responses have allowed me to successfully set up the following directory structure: ...\data\raw ...\data\derived ...\prog ...\lst ...\log In the \prog directory I have put an RGui.exe shortcut and "pointed it" at \prog as the "Start In" location. In the same

As Jeff says, it might be that you have a ~/.Rprofile file with instructions to load packages when R starts. It could also be that you have a .RData file, which is saved if you answer yes to: > Save workspace image? [y/n/c]: y when you quit R. If this file exists, then R loads it and all the objects you had when you saved it. If there are objects associated with packages, then that will

It could be that the following may be due to something wrong that I managed to do (I cannot think what...) but I submit this report in case it is something that you want to know about (I have solved the problem by removing .Rprofile as I describe below). 1. After compiling/installing R 0.90 (an uneventful process), it worked perfectly the first time, and it read .RData written by the previous

Can you be more specific about what conditions cause R to automatically load a package when a .RData file is loaded? My experience has actually been the opposite.

I am having difficulty coming to grips with Appendix B.2 of the otherwise very useful "An Introduction to R" and the related help file for Startup. I am running RGui 1.6.0 on a Windows 2000 machine from the default installation. How the concepts discussed in B.2 and the Startup help file relate to what I see on my machine is something of a mystery. I quote from the Startup file:

Back to my favourite R subject: batch mode. Some months ago, I pointed out how the default of saving .RData automatically in batch can often lead to completely erroneous results when using data.frames. Basically the idea of .RData is to save the environment to start where one left off. This will generally be quite different than where one started the session. The idea of a batch file is to redo a

For reasons that are best known to myself [ ;-) ] I have a value of .Random.seed saved (via dput()) in a file ``.Random.seed.save''. In my .Rprofile I have the lines: .Random.seed <- dget(".Random.seed.save") Junk <- dget(".Random.seed.save") print(all.equal(.Random.seed,dget(".Random.seed.save")))

[Env: WinXp, R 2.9.2] In my .Rprofile, I define a number of utility functions I'd like to have available in my R session, but don't want them to be *normally* listed by ls(), or more importantly, saved if I save my session variables/functions. How can I do this? -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. York University Voice: 416

I currently set the Bioconductor repository in my .Rprofile using this code (which needs editing for every version number change of Bioconductor): # Choose repositories repos <- structure(c(CRAN="http://streaming.stat.iastate.edu/CRAN", CRANextra="http://www.stats.ox.ac.uk/pub/RWin",

A shorter reproducible example: example(makeActiveBinding) for (fred in 1:3) { 0 } ls() Both problems go away if you first do compiler::enableJIT(2) So looks like a bug in compiling the for loop. -Deepayan On Sat, May 23, 2020 at 5:45 PM Thomas Friedrichsmeier via R-devel <r-devel at r-project.org> wrote: > > Possibly just a symptom of the earlier behavior, but I'll amend my

Hi, I want to use the .RProfile to set defaults such as text editor. Is this a file I need to create? Also, where should I put it? I tend to create .RData files for different projects, putting each in a different Windows (Vista) folder. Is one .Rprofile file created that any instance of R can access (I would imagine so)? Thanks, Walt -- ________________________ Walter R.

Hi, I stumbled upon a surprising behavior when using an active binding as a loop index variable in R 4.0.0. In contrast, the behavior observed in R 3.6.1 is in line with my expectations. Consider the code below: makeActiveBinding("i", function(value) { if (missing(value)) { x } else { print("set") x <<- value } }, globalenv()) i <- 1 # output

I'm experiencing some confusion with the ellipsis argument (...). In my .Rprofile, I have the following functions: stderr <- function(x, ...) { sqrt( var(x, ...) / length(x) ) } se <- stderr I can use tapply to calculate some means: > tapply( Diameter, factor(Region), mean, na.rm=TRUE ) I II III IV V 0.02896429
