Hello everyone, this is my first post here and I hope I signed up correctly and someone will take me by the hand and help me out. I am new to R and cannot figure out what to do here... ... I want to have an User Interface that requests input. I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog (

Hello, I'm very new in working with tcl/tk in R and have a problem which will probably sound silly to most of you. Here is the code I have problems with: readcelfiles <- function() { require(tcltk) tt <- tktoplevel() tkgrid(tklabel(tt,text="Choose a directory!")) OnOK <- function() { fileDir<-tclvalue(tkchooseDirectory()) data.raw <-

Friends: I am a long-time R user, learning tcl/tk, and am tying myself in knots over something that should be simple. I want to create a frame and put that frame inside the toplevel frame. This works (i.e. it places text in col 1, and the corresponding entry box in column 2) and later frame.2 resides where it should in the toplevel frame. tkgrid(tklabel(frame.2, text="FACTOR column

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

Hello, I am using R 2.11.1 under Windows XP. I would like to know if its possible to use a function with arguments as a command in tcl tk. For example require(tcltk) PressedOK <- function() { tkmessageBox(message="You pressed OK!") } tt <- tktoplevel() OK.but <- tkbutton(tt,text="OK",command=PressedOK) tkgrid(OK.but) tkfocus(tt) the function PressedOK has no

I everyone, i have a little problem with tklistbox,the " " character and Rcmdr. Please look at this code require(tcltk) tt<-tktoplevel() levels.list2 <-tklistbox(tt,selectmode="multiple",exportselection="FALSE", height=4, yscrollcommand=function(...)tkset(levels.list2.scroll,...))

Hello, I am sorry if this is an answered question, but I did my homework for a long while and couldn't figure out a way to retrieve data entry from a model dialog. In one of the examples compiled by James Wettenhall: odalDialog <- function(title, question, entryInit, entryWidth = 20, returnValOnCancel = "ID_CANCEL") { dlg <- tktoplevel() tkwm.deiconify(dlg)

Dear list members, Is it possible via a suitable tcltk command to get the *current* width, in characters, of a Tk text widget that has been resized with the mouse? In the following code, the reported width of the text widget doesn't change, even though it has been resized. I can, however, get the current width in pixels: > library(tcltk) > top <- tktoplevel() > textWindow <-

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to

I would like to reference array dimensions by name in an apply and a summary function. For example: apply(x, "workers", sum) Is there a better way to do this than creating a new attribute for the array and then creating new methods for apply and summary? I don't want to name the individual elements of each dimension (such as with dimnames) but rather name the dimensions. Thanks

hello, i would like program userfriendly tcl/tk widgets like the t-test example in a more complex way ! (1) Is it not possible to combine tk_getOpenFile with the R function read.table to select in userfriendly way data sets ? (I'm newbie and take code-parts from t-test example and scripting example.) (2) Is it possible to use a variableSelection widget to select a special variable which i

I just uploaded two packages to CRAN. shapefiles_0.1.tar.gz - functions to read and write ESRI shapefiles (including dbfs) emme2_0.1.tar.gz - functions to read binary data from an EMME/2 databank data (EMME/2 is a transportation modeling program) Please let me know if you find any bugs or have some suggestions.

In Windows, Tcl/Tk programs running under the tcltk package can update too frequently: for exmaple, we might go through a long sequence of operations to construct a complex display, and in Windows each addition will be shown separately. To work around this, I've added a function "tclServiceMode" which serves as an R interface to the "Tcl_SetServiceMode" function in the

I want to run Rcmd BATCH with R_DEFAULT_PACKAGE=base so it doesn't load any packages, but it seems to reject this argument because it does not start with a '-' or '--'. Is there a different argument that will work? Thanks.

I understand how R treats NAs but in the situation below it would be nice to have a na.skip argument to paste so it does not convert the NAs to "NA"s and simply skips those elements of the vector for pasting. > x [1] "2.13" "2.3" NA NA "2.83" NA > paste(x, "0", sep="") [1] "2.130" "2.30"

I am trying to open an existing binary file, seek to a position in the middle, and then write one byte, while keeping the already existing data after that byte. It seems to me that I am unable to open a connection to a binary file in both read and write mode. I can open the "r+b" binary file connection and seek around, but I can't write to the file. And looking at the function

I've been able to figure out on my own how to do what I need in the largely undocumented tcltk package, but I've finally hit a wall. I can't even think of any sufficiently specific search terms to use for this. I'm trying to make the widgets in my tk window resize when the window is resized by clicking and dragging on its corners or edges. Instead they stay exactly where they
