Hello dear R-help members, Very soon I am to give a lecture on R. And in that lecture I intend to move between: par(mfrow = c(1,1)) to par(mfrow = c(1,2)) back and forth. I anticipate this will damage the image proportions and will force me to resize the window. So far I have found it is possible to close the window and then reopen it (bigger/smaller) by using: dev.off()dev.new(width=5,

Hi, I have a question regarding the R command options under Linux Is there any options that I can save history only? The only save option is --save, which saves both data and history. I don't want to save temporary data, because sometimes the it takes much time if the temp data is too big. However I want to restore the history for my next R session.. If there is no such option that meets my

I use 1.7.0 version under Windows XP. Problem: When graphics device history recording function turned on, suppose I source a file containing lines: plot(graph1) plot(graph2) I see the graph2 in the graphic device, assuming graph2 is the last plot in the file. Now using "Previous" under history menu, I get graph1 as expected. But after that, using "Next" does not show graph2.

I connected from my desktop Linux box to a Linux server using ssh in an xterm, but that xterm was running in Xvnc. I'm running R on the server in that xterm (over ssh). Something went wrong with Xvnc that has caused it to hang, probably this bug: https://bugs.launchpad.net/ubuntu/+source/vnc4/+bug/819473 So I can't get back to that ssh session or to R. I had done a bunch of work

hi folks, i use ESS mode in emacs often to interact with R, and while i know how to save a session transcript, i'm wondering how to save just the history of the commands (i.e. identically to how R gives the history save option from its native CLI). if you use ESS with an R process, commands entered from a separate buffer and sent to the process do not get registered with the R history, and

Hi! I have the following issues using "R for Mac OS X 2.2.1" (from the ppc-.dmg) on a Mac OS X 10.4.5: 1) The command history is never saved (automatically) to .Rhistory. (The file stays empty.) 2) If I save a history to some file via the "Save History" button, and I load it afterwards via "Load History", only the first entry of the saved History appears in

i want to compare two variables (having numbers) serially for matching/dismatching both having equal length > x [1] 2 2 1 2 3 2 2 2 2 3 3 2 2 2 2 2 2 3 2 2 2 2 2 2 2 2 2 2 3 2 3 2 2 2 1 2 2 [38] 2 2 2 3 2 3 2 2 1 2 2 2 2 1 1 1 3 2 2 2 2 1 1 3 1 1 1 2 2 2 3 2 3 3 3 2 2 [75] 2 2 3 2 2 1 1 1 2 3 2 2 2 2 2 2 2 2 2 1 1 3 2 2 2 2 2 2 2 2 2 2 2 1 3 > y [1] 2 2 2 1 3 1 3 2 1 3 3 3 3 2 2 1 2 3

Previously, even non-length commands were added to history, but it shoudn't, e.g: just typing enter. For example, if you type: FOO -> (ENTER) -> (ENTER), then to get FOO from the history you would have to press the UP key twice. It also saves a bit of memory.

Dear all, I am a new user of R, here I have a question about remove the previous restored workspace. I saved the workspace last time, but R always automatically load the workspace when I open it. I try to remove the object and then close R without saving. But next time when I open R, it always load the previous workspace. I want to delete the .RData in the directory, but I have no clue

I have an environment variable `$R_HISTFILE` pointing to `/home/my.username/.RHistory` and the following code in my `.Rprofile` in my home directory: .Last <- function() { if (!any(commandArgs()=='--no-readline') && interactive()){ require(utils) try(savehistory(Sys.getenv("R_HISTFILE"))) } }

I'm having trouble finding documentation on how to activate the "record graphics history" option via a command line (as opposed to having to use the menu). I would like to store a series of graphics. The readme says: `The History menu allows the recording of plots. When plots have been recorded they can be reviewed by PgUp and PgDn, saved and replaced. Recording can be turned

Hi Everyone, I am a beginner running R 2.9.2 under Ubuntu and typically use Emacs w/ESS. However, I am confused with history() command. When I issue command history() in Emacs within an R session, this is what get: > history() Error in savehistory(file) : no history available to save Similarly, history(max=10) command gives the same error message. However, there is this In/Out Menu in the

Hi everybody. I was just wondering if this is a bug or I am simply doing something wrong. Here is what happened: (1) I typed windows() to get the graph menu bar (2) I turned record on history menu (3) I created a couple of plots (4) I checked with PageUp and PageDown that I can scroll through them (5) I saved the history to a variable, say, hhh (6) I dumped hhh to a file called hhh.R (7) I quit

Previously, even zero-length commands would be added to the history when they shoudn't, e.g: just typing enter. For example, if you type: FOO -> (ENTER) -> (ENTER), then to get FOO from the history you would have to press the UP key twice. It also saves a bit of memory.

Hello. First post, please excuse lack of experience. I recently switched from MS-Win to Kubuntu and find it rather difficult to recover Cran-R ease of use. The "Graphics history" facility available under Windows was, for me, extremely useful. From Murrell's 2005 book (see citation below) I understand that no such facility is available under non-Windows systems. In R-help

Hi, > history() gives Error in savehistory(file) : no history available to save although I can scroll throu history with C^uparrow an C^downarrow. How can I make history() work and/or show the current history in a file, so that I can choose from previous commands? The web did not throw up anything useful. TIA --Christian -- Christian W.

Hi, I've been asked sometimes to tailor call history features embeded in SIP hardphones. For example, a cutomer wanted internal call to be taken out. Another wanted calls to sorted according specific criteria. 1. Have you identified a phone offering the possibility to display as Call History, an XML list produced on a distant web server ? With this feature, you would simply have to tell the

Hi, I run the following command and try to save the commands that have been run in the script. But it seems that no history is recorded. Is it because that the history is not recorded in Rscript?

Hello, Im running R 1.8.1 on Win2000 and frequently using the function history() to keep track of what I did in my R session. In a recent session I typed history(max=Inf) and to my surprise there were only 15 lines of code where there should have been approx. 300 lines and I lost a lot of valuable work. Do you have any idea what caused this behaviour? help(history) didn't make me any
