similar to: R for Mac OS X

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

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,

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

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?

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

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

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's possible to create a package with functions and data, from which the use library(pkg-name) "attaches" not only the functions, but also the data? I want avoid to use data(dataset, package="name") because this makes a global copy of the data-set ... Anyone could help me? Meinhard

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

I am having trouble with the library function of R Version 1.5.0 for Mac OS X Carbon when I try to load libraries that did not come with the R installation. For example, I put the Biobase library from bioconductor.org in the 'library' folder. R cannot find it, even though it can find the pre-installed libraries: > library() # this lists standard libraries such as 'boot',

Hi, everybody. I just started using R on Mac OS X. I'm trying both of Carbon and Darwin version. I used to use S-PLUS on Linux and want to use splom to do multi-plot. I looked at both Carbon and Darwin version, but Carbon version doesn't seem to have Lattice library. I downloaded the binary for Darwin version. I have XDarwin/OroborOSX installed on my Mac's (G4 Powerbook and
