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

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 off-topic subject. I am fighting for running SJava under Windows. SJava_0.64 (compiled by Simon Urbanek, thanks), R 1.6.2, Java JDK 1.4.0_02, Windows XP pro: > library(SJava) > .JavaInit() Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find the Omegahat interface manager class.

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

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, 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

Hi all, After being a long time off the R and R-SIG-GUI lists, because I was working hard on SciViews, I am happy to deliver the first public version of this program. It is still v. 0.1, that is, an incomplete alpha version. It currently installs only on Windows 2000 or XP (NOT on Windows 9X/ME/Millenium, nor any other platform!). You can download it at http://www.sciviews.org. Please, note that

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

Happy New Year, r-helpers! I am using lowess to smooth a scatter plot, xx<-lowess(xinput,f=.04) #defaults for other args followed by turnpoints(xx$y) #defaults for other args I plot the smoothed result as well as turnpoints (using yy$tppos) on top of raw data plot. Result is exactly as expected, graphically. For another purpose, I calcuate the difference between turnpoints (representing

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,

Hi List, i am locking for a GUI for R. I have a Debian Woody 3.0 and running R 1.5.1. In office i am using SPSS 9.0 for several years now after Systat for short time and now i would use a statistic software under Linux at home. It seems that R could be that what i am looking for, but i have problems to understand how it works or better explained i would prefer using a good grafic interface.

Hello all, I've put together a quick and dirty menubar + dialogs + spreadsheet GUI for R using the RGtk package. Performance is not great (OOP is a real memory hog?), the design may be worse, but the hope is that it will be useful in an introductory stats course while we await the arrival of a real gui with ObveRsive and SciViews. The package can be found at

Hi Folks, Sorry to raise what has probably been discussed before, but I an repeatedly struck by the comparative slowness of S-plus for Windows compared with R for Linux when doing much the same thing. I don't have a direct comparison, because they're not running on the same machine; but machine W has a faster CPU and more RAM than machine L, yet S-plus on W seems to take longer by quite

Hi, I've got a problem which seemed simple to me at first view, but which I haven't managed to solve yet. I have a dataframe, or a matrix, and I would like to order it along with one of the variables/columns. I tried to use order() but it remained quite unclear to me. How should I proceed ? Thanks in advance (I guess that's not very difficult a question for most of you) Laurent

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 ... It is not documented in R! I propose appending
