similar to: Grid won't load on Windows NT

I'm using R 1.3.1 on a Windows NT 4.0 machine. As you might guess my machine crashes on me from time to time :-| So far, forcing a reboot via the Taskmanager has worked reasonably well: any open R session would enquire politely whether to save, and do so if requested. This time, it has not worked out. I get a 'Fatal Error: unable to restore saved data in .RData' message and R

Hi, I am using the EBImage package for image display and analysis and want to read the cursor (mouse) position on the image. The function "locator()" would be ideal, but this appears to work only on plots, not images. > a <- Image((0:(w^2))/w^2, c(w,w)) > if ( interactive() ) display(a) > locator(n = 10, type = "p") Error in locator(n = 10, type = "p")

I've learned that I can make a tag with vorbisgain that tells the player at what volume a track is to be played to achieve a certain level of loudness. Is it possible that there will be a tag that tells the player for instance to add more bass when it plays a track? Ore more treble? With such tags it would be possible to customize the sound of a track according to my wishes - without

Dear r-bugs, I'm having problems loading the 'grid' package when it has been detached earlier in the same session: > library(grid) > detach("package:grid") > library(grid) Error in .Call("L_initGrid", PACKAGE = "grid") : .Call function name not in load table Error in library(grid) : .First.lib failed This bug was mentioned on r-help

I am new on R, so I have a maybe naive question: if I have many large data.frames and I use only one or two per session, what's the best way? If all are stored in the actual .Rdata, the system gets slow. On the other hand, I wouldn't like to make a separate package for the data. Should I save it with save() and then remove it with rm() ? Could I reload it then? Thanks for suggestions

i was searching for the source of bca.ci, a function of the package boot. I tried require(boot, keep.source=TRUE) but again the source was not viewable. How should i do?

Hi R user! What is the fastest way to export a large matrix or vector to a MySQL database? The use of data.frame() and dbWriteTable() makes the process slow, so is there any <direct> alternative? Regards Meinhard Ploner

Hello! Maybe "frame" is not the right term in this context. I explain my problem by example code: fun2 <- function(objName, add) { ## the object "objName" should be increased by "add", ## but the evaluation should be done in the calling function (here: fun1) ## ...... what's the right code?? } fun1 <- function() { x <- 1 fun2("x",

In R prior to 2.6.0 with matrizes as well as with data.frames it is possible to do: a[2, c(TRUE, FALSE)] In R 2.6.0 the mixed indexing works only for matrizes. Is this the intention, a bug, or did I get something wrong?

Hi all, I have Win XP and R 2.3.1 on my notebook. I would like to write a package which includes some Fortran 95 code. Interestingly, if I compile and link the simple file test90.f90 directly with g95 -c test90.f90 g95 -shared -o test90.dll test90.o then PE Viewer ( a dll viewer) shows me the right functions in the export table, hence I can use the dll in R. But as it should become part of a

It's possible to overlap an external image (jpg or pdf) with a plot generated with R? Specifying the image as the background of the plot might not be possible... any idea? thanks Meinhard Ploner

hi! I tried to build a very simple package with NAMESPACE file, such that datasets are loaded only dynamically. > a2 <- function(x=a1) x+4 > a1 <- 1:10 > package.skeleton("aaa", list=c("a1", "a2")) Then I modified the help files and added the file NAMESPACE with these 2 lines: useDynLib(aaa) export(a1, a2) Then "R CMD BUILD aaa" works

Dear list, we are a statistical/epidemiological departement that - after a few years of rapid growth - finally is getting around to formulate a general data storage and retention policy - mainly to ensure that we can reproduce results from published papers/theses easier in the future, but also with the hope that we get more synergy between related projects. We have formulated what we

Thanks a lot, James!! The problem is fixed. On the version 1.4.0 Mac/darwin (the latest available version for this system) the function read.table (which is called from read.delim etc., too) has the bug you explained. Inserting the row nlines <- nlines+1 after lines <- c(lines, line) removes this bug. M. On Friday, February 22, 2002, at 02:33 PM, james.holtman at convergys.com

I have been running R CMD check for the first time on of our own packages, which otherwise builds, installs and runs just fine. The package depends on package akima and suggests package multtest; suggesting multtest is indicated because a) it loads a lot of other Bioconductor packages, very slowly, and b) it is only needed for one specific subroutine, which executes require(multtest)

Dear all, we have installed R in one of our computer labs. Running demo(grpahics) works, kindof, in that it produces all the usual plots without crashing, but the plots are incomplete: no color wheel, no pie chart, no boxplots, just some labelling, titles, and in rare cases, axes. We have tried this with both 1.7 and 1.6.2, with the same results. The computers are running Windows 2000, with

Hi all! My system: R 2.1.1, Mac OS X 10.4.2. I have a very memory-consuming job for R, consisting of a function calling some other functions, working often with matrices of size 100.000 x 300. If I call the job directly after starting R the job takes overall 40min, however only 7min of process time. I assume the large difference is through memory-handling which doesn't count as

Hello! What is wrong on my system? I have downloaded today R 1.9.1 on my PC with Windows. plot.table isn't available in package <base> and neither in package <graphics> (as suggested after ?plot.table). Kind regards Meinhard Ploner [[alternative HTML version deleted]]

Had no replies, so here goes again. We recently installed the Terminal server SP6.0 on Windows Terminal server. And are now having problems opening some files with some applications from samba shares. We have traced it to being a file open function used by apps. such as notepad and perl. Any ideas what has changed in SP6 and how to fix it? samba server Samba 2.0.7 on Solaris 2.8 --
