I'm build with the usage of the tcltk/tcltk2 package a gui which is started with rscript.exe. At this gui the user is able to open and close plot windows. Now I'm looking for a way that a r function is called when a grDevices::windows window is closed. Is there a way to attach a callback function or so, which would be triggert if the user click at close of the grDevices::window? My

I want to plot points with different colors to show different selections of points in a 3d plot. My problem is that if I plot a red point at a location where already a blue point was plotted, than the point is still blue. Is there a parameter or so which can be used to draw over a existing point? Example: > require(rgl) > open3d() > plot3d(a<-c(1,2,3,4,5),a,a,type="l",

Perhaps I'm being even thicker than usual, but I can't find the tcltk package on CRAN. There is a tcltk2 package, which says that it is a collection of supplements to tcltk, but I cannot see a just-plain tcltk anywhere. If I try to install tcltk2 (from the Linux command line, or using install.packages() in R) it complains that it needs tcltk. If I try to install tcltk using

Dear Rodrigo, Try tkwm.geometry(win1, "-0+0"), which should position win1 at the top right.

I've written a fairly elaborate package (called "eoa") that relies on functions from several other packages. I've built the package into a zip file on Windows using Hadley's devtools::build(binary = T) and have sent the zip to a couple dozen people for testing. My package installs fine, but some people are having trouble loading it. After library(eoa), they get something

R and DDE (Dynamic Data Exchange) Dear Rusers, I run an application (not mine) which acts as a DDE server. I would like to use R to get data from this application, say once per minute, and do some processing on it. I didn't find much info on the R DDE abilities, apart the tcltk2 package in which I will try to go deeper. I would be very thankful for any info, pointer or advice about the

(s. below) DEADTIME expiration is a critical condition if the UPS is on battery when comms are lost, otherwise you are correct, it is only informative. What about a NOTIFYCMD script

Quick followup. Confirmed that TCl/Tk are both installed on the machine (they are, in both 32- and 64-bit flavours), as are all tcl and tk-related libs, devel packages, and about everything else I could find. It occurred to me that perhaps the R I compiled isn't 'tcltk' aware. I checked the config.log, and there is some hint that this might be the case. Just before ## File

Hallo, I have one ups with snmp and any ups without snmp. Shutdown works while network online. But some batteries are empty, so that the communication break early. Howto force shutdown if nut-snmp Communications lost? My 1. suggestion was option DEADTIME, but seem to be information only. (s. below) Any suggestions? The last way would be a ugly cronjob (like: ping || shutdown). regards Heiko

Dear R-devel: Would R core team consider endorsing a graphical toolkit and trying to facilitate development of little GUI tools? I need a gui matrix editor for users that want to be able to write matrices that are later used to simulate data. Instead of teaching them to write a covariance matrix (for example, for mvtnorm), I want to tell them run a function that pops up a table they can fill

hi: my company has two dns servers, but samba4 internal dns forward can only forward to 1 server. to workarround it i run dnsmasq as dns cache at 127.0.0.1 and let samba4 dns forward to 127.0.0.1. my smb.conf looks like: dns forwarder = 127.0.0.1 interfaces = 10.1.1.1 bind interfaces only = Yes with the setting samba won't bind to 127.0.0.1, so dnsmasq can use 127.0.0.1 to do the work.
