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",

Hi! I have R 1.9.1, Mac OS X 10.3.5, GNU Emacs 21.2.1 and ESS 5.2.3. I installed today the ESS by not changing ess-site.el, but creating .emacs in $home with the single line: $ cat ~/.emacs (load "/usr/local/lib/ess-5.2.3/lisp/ess-site") If I start now emacs and then R (with M-x R) then I get: > options(STERM='iESS', editor='emacsclient') but using fix() oder

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 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! 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

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

Hi! Since August I am using emacs on my Macintosh to edit the R objects. I have installed R 1.9.1, Mac OS X 10.3.5 and GNU Emacs 21.2.1. However there are some issues I haven't resolved: a) switch the caps lock key to the meta key (and when this is not possible, switch the alt/option key to the meta). The switch should work only within emacs! b) having different colors for the code,

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

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]]

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

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! 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

It seems that R 1.3.1 is not very stable for Mac OS X. I installed it some days ago and had about 10-20 crashes in the last days. In S-Plus I never had these problems (or seldom), but I worked on Win NT. Who can help?

Hello, I have some problems with RODBC and Excel in Win98 I am using R 1.6.2 and just upgraded RODBC to the last version on CRAN. I have an Excel file with columns Number, Name, Sex, Age, FEV1 on Sheet 1 and Number, Age, FEV1, Name, Sex on Sheet 2. Now I open the channel to the file > chan1 <- odbcConnectExcel("c:/testOdbc.xls") > tables(chan1) and the list appears with the 2

I have a graphic image in a file (say a *.jpeg or *.png file) and want to put it into a plot. I have segmented the plot area by means of the layout function and successfully plotted my data in the appropriate segments. I cannot find how to put my graphic image onto the same plot. Searching the archives has shed little light on my challenge. Many thanks in anticipation. Gordon > version

Hi, I'm trying to get an Effekta UPS (works directly with blazer_ser) working behind a seriell to ethernet converter (Brainboxes ES-246). I've set the converter to 2400 baud, 8N1, no flow control. On the linux side I started socat and blazer_ser. All I got are timeouts after 12 seconds. I can see network traffic with tcpdump but I've no idea what to do to get this working. Does

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

Dear list, I wish to define a set of functions *auxilliary* to another set of "main" ones, and I wonder if there is some "clever" way do do this using lexical scoping. Looking for that in the list's archives did not get me easily understood answers. Perusing MASS (1st, 2nd, 3rd and 4th editions!) and "Programming S" wasn't of much help either... R easily
