similar to: SciViews R GUI preview version available

Hello, This message is little off-topic in R-help. Sorry for that, but not all interested people are wired yet to r-sig-gui (http://www.stat.math.ethz.ch/mailman/listinfo/r-sig-gui). Thanks for your comprehension. A preview version of SciViews (a Graphical User Interface for R under Windows, http://www.sciviews.org) was released a few weeks ago. Since then, the Web site recorded several

Hello, I do not understand the following behaviour. Could someone explain me what happens? > a <- NULL > a$item <- 1:3 > a$item [1] 1 2 3 > rm(a) > a <- NULL > a[["item"]] <- 1:3 Error: more elements supplied than there are to replace Why do I get an error message using list[["item"]], and not using list$item? Best, Philippe Grosjean

Sorry for entering late in the thread, but I was absent last week. I am developping an alternate GUI for R (and also Splus, Octave, Scilab, Matlab, Ox & Mathematica). The project started 3 years ago, but it is progressing slowly, since I am currently the only developer on the project and had to do it during my extra time. Now, it is going a little faster because I got some time and money

Hi, I was able to connect to a MySQL database (called "zooscan" and with a table "serie" under Win XP with R 1.6.2 using: > library(DBI) > library(RMySQL) Warning message: DLL attempted to change FPU control word from 8001f to 9001f > drv <- dbDriver("MySQL") > con <- dbConnect(drv, dbname="zooscan") > dbExistsTable(con,

Sorry for this out-of-topic message. A while ago, somebody mentioned a software (an R interface xas in development at that time) to graphically look inside classification/regression trees and calculate various statistics on their nodes. Unfortunatelly, I lost the link and do not remember at all the name of the software. Could someone refresh my poor memory,... or perhaps point me on other

Sorry for this off-topic subject. I am fighting for running SJava under Windows.

I do not understand what happens here (under Win XP): a <- abs(matrix(rnorm(800*800)/2, ncol=800, nrow=800)) system.time(b <- a^1000)[3] took about 1 sec on my computer with R 1.7.0 and it takes now 4.59 sec with R 1.7.1 Similarly, phi <- 1.6180339887498949 a <- floor(runif(750000)*1000) system.time(b <- (phi^a - (-phi)^(-a))/sqrt(5))[3] took about 0.9 sec with R 1.7.0, and it

Hi, This is (presumably?) a bug in R 1.7.0 under Windows. I have not tested it on other systems. Attachment of packages is case sensitive but not library(), resulting in multiple loadings of the same package if the library name is spelled differently. The following example loads the `tools' package, once as `tools' and once as `Tools'. This behavior is the same with all packages and

OK, I have made a little search about this "problem" that apparently occurs only on Windows platform... (but I am sure most of you are already aware of it): the slow down is due to the adoption of a different algorithm for pow in mingw 3.x. This is motivated by some other changes in mingw. Here is a quote of Danny Smith that did this change: >When mingw changed default FPU settings

Hello, I suppose this is a general behavior with external function calls, so I do not post (yet) a specific bug report. Could someone explain this? a <- rep(1, 20) + rnorm(20, mean=0.00001, sd=0.0001) b <- embed(a, 3) # I want to know where the item in column 2 is greated than both col 1 and 3 (peak) test1 <- max.col(b) == 2 # ... or I could use a less optimal code test2 <- apply(b,

as.integer() truncates doubles toward zero, as Splus does (at least v. 6.1 under Windows does). Thus: > look <- (10 * seq(14)) - 76 > 10 * (73.1 + look) [1] 71 171 271 371 491 586 681 791 886 981 1101 1201 1301 1401 > as.integer(10 * (73.1 + look)) [1] 70 170 270 370 490 586 681 791 886 981 1101 1201 1301 1401 ...

Well.. plans are there from a long time to rewrite SciViews completely and make it platform independent (to work on Linux/Unix and MacOS X, as well as Windows). I have done some work in this direction when time permitted, but I am pretty busy with other work. During the holidays, I will continue to work in this direction. I will try to package a first running version of SciViews compatible with

Hello, An alpha version (unstable, still in development) of SciViews-R can be downloaded from http://www.sciviews.org/SciViews-R. See also screenshots at http://www.sciviews.org/software/rconsole.htm. The SciViews R package provides functions to implement GUI features (object explorer, script with context-sensitive help and completion lists, ...) and to ease the communication with external

Dear all I am writing with a question regarding SciViews for R. It's probably a slightly stupid question but I cannot find a solution to a very elementary problem. I am using SciViews 0.8.9 on with R 2.3.1pat on a Windows XP Home machine. R is set to SDI mode, I start R, enter "library(svGUI)", SciViews starts properly, I can access the docks and everything, but (i) the command

Bonjour, J'ai t?l?charg? SciViews Insider que je trouve tr?s convivial. Par contre, je n'arrive pas ? comprendre comment enregistrer un script R en type de fichier R justement. Mes programmes fonctionnent tr?s bien, mais SciViews me propose uniquement de les enregistrer au format txt sous un type de fichier "bloc notes". Comment les enregistrer avec l'extension .R comme le

Dear R users, I successfully installed SciViews the other day. However, when I try to run it now, the command/script window does not appear. Strange. Well, actually I see a tendency to a script window (in the lower part of the sciview window where it is suppose to be) during start up, but when the program is entirely open, the script window is gone. I have tried to uninstall and reinstall
