Hi I am using Rserve for R2.3.1. every time after I load Biobase library, a new Graphics window frame pops up. Could any onw know how can avoid it.

write.table with large data frames takes quite a long time > system.time({ + write.table(df, '/tmp/dftest.txt', row.names=FALSE) + }, gcFirst=TRUE) user system elapsed 97.302 1.532 98.837 A reason is because dimnames is always called, causing 'anonymous' row names to be created as character vectors.

Hello, I'm having trouble calling rsync from java on windows vista with cygwin installed. Its strange as pasting the exact same command into a command shell works fine.

I have been doing some programming with java servlets for data collection. I was wondering if there is a way to connect to the R-server using java to do data analysis. A java-interface or some connection class. I think there is some similar facility with SAS, although I have not looked at it. Richard Piper RNS Hospital, Sydney.

I'm expirimenting with Cepstral via swift.agi. It loads w/ no problem, but there is a fairly long separation between words -- almost as if it is processing one word at a time, rather than stringing a phrase together. When I run cepstral with a similar script, but not through an actual call from asterisk the separation between words is short and natural. I'd really appreciate

Hi, I've managed to compile it the class down to a native executable. However, the executable runs for a while then spits out: terminate called without an active exception Aborted and dies.

Hi All, I have a server setup with an incomming PSTN line and a bunch of Grandstream BT100 phones.

Hi everybody, I'm trying to build a trilineare coordinate system with R. For that, I need to rotate an axis. Does anybody know, if it is possible to rotate an axis, created with the command axis(), about for instance 60 degrees?

I apologize if this is too obscure to reproduce, or some idiosyncratic aspects of my system. If I create a plot, e.g., > plot(1:10) I get a graphics device as expected. I then click on the 'zoom' box on my X11 window, so the window expands to occupy the entire screen. The plot is redrawn at the scale of the large window, but is clipped to the 'unzoomed' size. I only
