Hi, I have a problem with a package I have developed in that functions do not get loaded due to older versions of the functions being in the .GlobalEnv? fetched from .Rdata files stored from previous saved workspaces. I need to be able to fix this somehow when I load the package. I do not want to mess up the search order to fix the problem. How I got myself into this mess is that I started

Hi, How to save an R object for example a matrix or vector and not all objects created in a session (which is usually performed by save.image or q("yes"))? Best, Carol [[alternative HTML version deleted]]

In the below, I generate a model from an environment that isn't .GlobalEnv with a large object that is unrelated to the model generation. It seems to save the irrelevant object unnecessarily. In my actual use case, I am running and saving many models in a loop that each use a single large data.frame (that gets collapsed into a small data.frame for estimation), so removing it isn't an

Another solution is to only save the parts of the model object that interest you. As long as they don't include the formula (which is what drags along the environment it was created in), you will save space. E.g., tfun2 <- function(subset) { junk <- 1:1e6 list(subset=subset, lm(Sepal.Length ~ Sepal.Width, data=iris, subset=subset)$coef) } saveSize(tfun2(1:4)) #[1] 152 Bill

Sorry for the cross-post. Not sure where the problem is... A while back I posted an R function to R-help: cd <- function (dir = tclvalue(tkchooseDirectory()), saveOld = FALSE, loadNew = TRUE) { stopifnot(require(tcltk)) if (saveOld) save.image(compress = TRUE) setwd(dir) rm(list = ls(all = TRUE, envir = .GlobalEnv), envir = .GlobalEnv) if (loadNew &&

Dear all May I know how to solve this problem? I have encountered this problem after I have logged out from Rstudio. Thank you Warning: namespace ?caret? is not available and has been replaced by .GlobalEnv when processing object ?fit.ann? Warning: namespace ?ggplot2? is not available and has been replaced by .GlobalEnv when processing object ?p1? Warning: namespace ?plotly? is not available and

I got two .RData file e.g data.2005.RData & data.2006.RData I would like to combine these two different data set and make single RData file. in both file there are some NULL files are also available and I would like to clear this NULL files also. $ : NULL $ : NULL $ : num [1:43285, 1:8] -21.1 -21.1 -24.9 -24.9 -24.9 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : NULL ..

Previously, the R software was perfectly run without error and I am not sure why this happens. I have not installed any new R. If the *RData file is the problem, what should I do?

You haven't given much context, but these error message can come from load() when loading a *.RData file that contains objects reference packages not installed in the current installation of R. When R starts it will load a ".RData" file if one exists, this file is typically created when R shuts down and you ask it to save the current session. If you recently upgraded R you the

To follow up on my previous question, suppose a user R session wants to unload one workspace and load another within an R session. Is the following the correct sequence? 1. save.image() to save the current workspace as .Rdata in the current working directory. 2. rm(list=ls()) to remove everything from the workspace. 3. setcwd("xxx") to set the new working directory. 4.

I am the proud owner of a new laptop since my old one died the other day. Currently I have a dual-boot Windows 7 Home and Ubuntu 12.04 . I'll leave the Windows problems for another post. I know practically nothing about Linux so I am probably doing something stupid but ... at the moment I cannot seem read or write files in Ubuntu. I am not having any problem saving other documents to the

Hi, I wanted a Q&D way to open a new graphics window but keep the focus in the console window (under Windows and the Rgui), so I wrote a line into my Rprofile.site file as follows: invisible(makeActiveBinding('newdev', function(...) dev.new(restoreConsole=T), .GlobalEnv)) (That is all on one line, incase the mailer re-parses it). This gives me a command "newdev" which

If an attempt is made to attach to position 1, it appears to work (not even a warning) but in fact it doesn't work as many would expect. "search" thinks that it gets placed in position 2, but nothing is actually there (according to "ls"). This is guaranteed to be confusing (and annoying) to people who are used to attaching to position 1 in S-PLUS. I'm not clear on

Hello everyone Can you please teach me how to save my homework as .R file? I write my code in RGui. When I tried to save my work, the RGui only allows me to save it as .RData. Is there any difference between .R and .RData? By the way, after I save my work as .RData, I cannot reopen it. when I open it, only one message comes out as following: "ARGUMENT_ignored_." -- View this

Hi, it looks like save() is saving all contents of the calling environments if the object to be saved is *not* evaluated, although it is not that simple either. After many hours of troubleshooting, I'm still confused. Here is a reproducible example (also attached) with output. I let the code and the output talk for itself: peek <- function(file, from=1, to=500) {

I am using a package which tends to crash R, so I have been saving my work at regular intervals with "save.image()". Unfortunately, this overwrites .RData with an empty workspace, so when R crashed I lost my workspace and a day's work. The problem is easily fixed: "save.image" looks like this function () save(list = ls(), file = ".RData") The expression
