Hi R-Devel, I've been working on an oscilloscope project using an Arduino microcontroller board. I found that it's quite easy to get realtime updates, e.g. 30+ frames per second, if I read data from the board in a little Rcpp library. I have to use dev.hold() and dev.flush() to keep the plot from flickering, which restricts me to the "cairo" X11 device. I'd like to be able

I was curious what R packages, or indeed any other applications, exist to plot streamed data from arbitrary data generators. It need not be publication quality plotting but it should be easy to use like an oscilloscope. I was working on something called datascope that I am using for 1D finite difference monitoring and recently interfaced it to freefem. I also created an R package. If there is

Wine does great job for GUI on screen (PC Oscilloscope) But, can't USB connect to external hardware device that has FTDI 245AM chip in it. See device in /dev/ttyUSB0. See device in lsusb, also in lsmod. Did normal linking, ln -s /dev/ttyUSB0 /.wine/dosdevices/com3. No luck. See the link with: ls -al of dosdevices. Using COM3 because in Windows registry in Wine, it says COMPORT=3 Any help?

Hello, I have been trying to use a collection of Fortran subroutines to return a 2D array of calculated values to my R code, calling a Fortran wrapper subroutine from R. I've done this successfully before with C & C++ code. The Fortran wrapper subroutine which is to be called by R takes a set of input arguments & then should return an array of 2 columns & the specified number of

Hello, I installed Electronics Workbench 5.2 (old version, but I have to import some work which I did using it) on Wine, mostly it works well, but: - When I close it, it enters an Access Violation/"Internal Error" loop. - Can't see text in some controls. For an example, check this image: http://img14.imageshack.us/img14/2707/75952076.png The controls in the 'Oscilloscope'

Hi, One of my APC devices reports: "unacceptable utility voltage rate of change". I believe it has something to do with input voltage fluctuating too fast maybe even beneath or over the input voltage thresholds. Should I worry about this? should I measure input voltage? (I suppose I'd need more than multimeter readings. Maybe an oscilloscope or a multimeter that can record

Dovecot Team, I'd like to report a number of bugs, that are to my view all critical. System: Replicated on multiple Debian 10 (Buster) systems Dovecot Version(s): 2.3.4.1 doveadm-sync -1/general 1) If DIRNAMEs are not different between command line and mail_location doveadm sync will fail, saying that the source and destination directories are the same 2) The -n / -N flags do not work,

Hello! Given the current discusison regarding ztmonitor, line testing, etc., I've been looking into purchasing a used transmission test set. From my research, it seems that there are two items that might fit the bill: the HP 3551A and the HP 4935A. I know nothing about these specific devices. I *do* have a good background in electronics, and I understand the concept what they're

Hello Timo, I have scheduled some time to carry through the test requested by Aki. I will add responding to you as part of that process. Not sure if I have said or done anything to offend you, as your tone appears quite abrasive, even where you do not have an actual response to an observation. It is my view that it is a privilege to provide an open source platform, and therefore a

Hi. I''ve subscribed my self to participate of GSoC''11. The project that Im interested is the parallax sm backend. My project is the integration with Xen Cloud Platform and Parallax. In end of this project, We expect a simple way of managing VMs with Parallax and if possible, to ease fail-over, migration and perform very low overhead snapshots. I’m open for suggestions and

Tengo en una maquia ubuntu 8.10 el kernel es Linux 2.6.27-14-generic Quiero configurar una tarjeta x100p i usarla con asterisk, asi que descague compile e instale lo siguiente: asterisk-1.4.24 dahdi-linux-2.1.0.4 dahdi-tools-2.1.0.2 libpri-1.4.9 Sin embargo no logro configurar la tarjeta con exito, ya probe casi? todo. Esto aparece si ejecuto lspci: 04:06.0 Communication controller: Motorola

Your report is most appreciated, though it lacked quite a lot of detail that could've expedited the investigation why it happened. With the further information we can hopefully figure out why you are experiencing the problems you reported. There is no offense intended.

Estimados Reailizo una pregunta general, casi desconociendo. Se me ocurrió explorar lo siguiente: hay ejemplos de programación lineal o utilizando la herramienta solver de excel, donde se realizan algunos cálculos, lo más sencillo de comprender y documentado (todos lados) es una cantidad de productos, un costo de compra, un costo de venta, una cantidad para invertir y ¿cuánto me conviene

Estimados Le consulto porque estoy intentando presentar unos datos de alguna forma un poco distinta, salir un poco de la costumbre. Primero describo los datos: Suponiendo una secuencia: golpe al auto -> torura de vidrio -> rotura de aciento otro auto golpe al auto -> -> rotura de aciento , a este por alguna causa no se le rompio el vidio o esa información es desconocida.

Hola a todos, Escribo debido a una duda en la aplicacion de la funcion seq en cada uno de los "n" componentes de un vector "x". Hasta donde yo se, dicha funcion no permite el uso de vectores. En consecuencia, y como primera aproximacion a lo que deseo hacer, he construido un bucle  que retorne una lista de "n" vectores (de distinta longitud), donde cada uno de estos
