Hi the list, One of my package has an (other) error detected by memtest that I do not manage to understand. Here is the message that I get from Memtest --- 8< ---------------- > try(choice(cld1)) Error in switch(EXPR = choix, Up = { : EXPR must be a length 1 vector --- 8< ---------------- The choice function does call the choiceChangeParam function, which is: --- 8<

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

Hi the list. I try to learn the S4 programming. I find the wiki and several doc. But I still have few questions... 1. To define 'representation', we can use two syntax : - representation=list(temps = 'numeric',traj = 'matrix') - representation(temps = 'numeric',traj = 'matrix') Is there any difference ? 2. 'validityMethod' check the

Hi the list I define a class A (slot a and b), a class C (slot c and d) and a class E that inherit from A and B. I define print(A) and print(B). For print(C), I would like to use both of them, but I do not see how... Thanks for your help...

Hi the devel list I am testing package.skeleton in R 2.7 (download today). I get an error that I do not understand. I guess it is not an error from my code since I have no probleme when I source it. So is it a error in package.skeleton? Here is my code : --- 8< ------ File essai.r ------------- setClass( Class="ClusterizLongData", representation=representation(

Hello the list, I am trying to write a "cleanProgramming" function to test the procedure I use. For example, I want to be sure that I am not using globals variables. The function "findGlobals" detect that. To list the globals used in function "fun", the syntax is : "findGlobals(fun,FALSE)$variable" My problem is that I want to use it in a function,

Hey all, new R user and first timer here. I've been using getGraphicsEvent() on an X11-Xlib device in a kind of interactive loop, and would like to be able to stop it from printing newlines in the console when I don't actually want to print a prompt. Even an empty "" value still causes a newline right now. To not break any code that depends on this behavior, I figured getting

Hi the list, I guess I find an other bug (the first one is at the end off this mail) in package.skeleton. It occurs when we give as code_file some file that are not in the current directories. If we give a single file to code_file (like code_file=3D"riri/fifi.R"), it does not reconize fifi.R as a regular name and change it to riri/zfifi.R If we give several file to code_file (like

... I just realized that setGraphicsEventHandlers or getGraphicsEvent could have an 'onIdle' callback, to be called somewhere in the polling loop of gevents.c:163 - I think this would solve my problem #2 in a minimally disruptive way.

Great. Thanks!

Hi Paul, OK I tried not to make the examples too fancy. Please let me know what you think. They should probably be amended to support the Windows platform, but I think that task would be much easier for someone with access to Windows... By the way I'm Cc'ing Mark O'Connell who shared with me some great getGraphicsEvent examples - well, I found them useful, perhaps if these are going

doKeybd() gets called in CHelpKeyIn() and NHelpKeyIn() in library/grDevices/src/devWindows.c, where the call is encapsulated in an 'if (dd->gettingEvent)' block. So the only times this code ever calls doKeybd() is when gettingEvent is in fact set. Further, it's called in two locations in X11_eventHelper(), in modules/X11/devX11.c, where the state of gettingEvent seems to be moot

Hey all. As in general it's a bad idea to allow an event handler to generate an event, and as comments in the code seem to suggest this isn't the intention either, I was wondering about recursion in getGraphicsEvent(). In main/gevents.c, both doMouseEvent() and doKeybd() have the following line; dd->gettingEvent = FALSE; /* avoid recursive calls */ And they reset it to TRUE

Hi all, I'm writing an interactive plotting function for viewing fMRI datasets. Currently, I get keypresses using grDevices::getGraphicsEvent(). Unfortunately getGraphicsEvent() only supports the X11(type="Xlib") graphics device on Unix systems. The Xlib device doesn't support buffering (i.e. dev.hold() and dev.flush()), so redrawing the plots causes lots of flickering. Is

Hi Taking a look at those patches is now on my todo list, so I may be in touch with both of you at some point to request some testing.

Thanks Frederick. Mark, if you have any examples to share, they would also be gratefully received.

Hi Just taking a bit more of a look at this today (currently fixated on making sure I can build some good regression tests). The best thing you can do is to keep reminding me like this :) Paul On 09/12/16 11:19, frederik at ofb.net wrote: > Hi Paul, > > Thanks for your efforts.

Hi The current status is that I am keen for people to contribute some testing code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951) There were also some getGraphicsEvent() changes/fixes suggested by Richard Bodewits (cc'ed), for which I am also seeking test code.

Hi the list. Is there a bug in mmlcr package ? The following code does not compile: mmlcrTest <- function(dataW){ dataL <- reshape(dataW,idvar="id",timevar="T",varying=list("T0","T1","T2"),direction="long",v.names="score") resultR <- mmlcr(outer= ~ 1 | id, components = list(list(formula =
