similar to: Tcl error - brace in argument?

Hi, The following function works, but is there a neater way to write it? f = function(x,...) { # return a character vector of the arguments passed in after 'x' gsub(" ","",unlist(strsplit(deparse(substitute(list(...))),"[(,)]")))[-1] } > f(x,a,b,c*d) [1] "a" "b" "c*d" > Thanks. [[alternative HTML

Hi, Please see below for post on r-help regarding data.frame() and the possibility of dropping rownames, for space and time reasons. I've made some changes, attached, and it seems to be working well. I see the expected space (90% saved) and time (10 times faster) savings. There are no doubt some bugs, and needs more work and testing, but I thought I would post first at this stage. Could some

Hi, In the example below why is d 10 times bigger than m, according to object.size ? It also takes around 10 times as long to create, which fits with object.size() being truthful. gcinfo(TRUE) also indicates a great deal more garbage collector activity caused by data.frame() than matrix(). $ R --vanilla .... > nr = 1000000 > system.time(m<<-matrix(integer(1), nrow=nr, ncol=2)) [1]

Hi, n = 10000000 L = list(a=integer(n), b=integer(n)) L[[2]][1:10] gives me the first 10 items of the 2nd vector in the list L. It works fine. However it appears to copy the entire L[[2]] vector in memory first, before subsetting it. It seems reasonable that "[[" can't know that all that is to be done is to do [1:10] on the result and therefore a copy in memory of the entire

Hello! The IWigdets::combobox has an option "selectioncommand" to specify a procedure which is called when an item in the combobox is selected. Does ComboBox from Bwidgets have an equal option or is there a simple method to do thi? I haven't found one but i would like to use Bwidgets instead of Iwidgets. Another question which should not be a problem, but at the moment I just

Hi, I'm using R version 2.9.0 and I'm trying to execute an example using tabnotebook from iwidgets. Unfortunately I get a problem as you can see bellow: > library(tcltk) Loading Tcl/Tk interface ... done > library(tkrplot) > tclRequire("Iwidgets") <Tcl> 4.0.1 > > tt <- tktoplevel() > tkpack(tn <- tkwidget(tt, "iwidgets::tabnotebook"))

Hi, I have successfully installed R 1.7.0 and ActiveTcl 8.4.2.0 in Windows 2000. Yes, I know that Tcl is already bundled with R 1.7.0, but I want to use the iwidgets package to create a drop-down listbox, and I don't think iwidgets is included in the bundled R 1.7.0/TclTk installation package. I have set the environment variables TCL_LIBRARY and MY_TCLTK to the directory where I

Kurt, Uwe suggested I write to you as maintainer of chron ... at the start of is.weekend, in the check on the argument type, maybe just change chron() to as.chron()? This would ensure as.chron.POSIXt gets called on POSIXt arguments, and (I think) fixes the problem. I tested and it seems ok. No warning/error required. > is.weekend function(x) { if(!inherits(x, "dates"))

Hi, Is there a function taking a function as an argument, which returns all the functions it calls, and all the the functions those functions call, and so on? I could use Rprof, but that would involve executing the function, which may miss some branches of code. I'd really like a function which looks at the source code to work out all the functions that could possibly be called. When I

Hi, Is there a way to define "+" so that "a"+"b" returns "ab" ? > setMethod("+",c("character","character"),paste) Error in setMethod("+", c("character", "character"), paste) : the method for function '+' and signature e1="character", e2="character" is sealed

Hi I've a problem with the following example: library(tcltk) .Tcl("array unset tclArray") myRarray <- matrix(1:1000, ncol=20) for (i in (0:49)) for (j in (0:19)) .Tcl(paste("set tclArray(",i,",",j,") ",myRarray[i+1,j+1],sep="")) tt<-tktoplevel() table1 <- tkwidget(tt,"table",variable="tclArray",

hi, i'm trying to make "Tabbed Notebook Widget",but cannot install "tclRequire(Iwidgets)". I installed Activetcl but I don't know what can be the next step to execute "tclRequire(Iwidgets)". how can i do that?

Hello, I'm very much a newbie in R and more so in tcltk so apologies if this question is stupid. Basically I am trying to use the combobox example found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html . What I want to do is in that example get fruitChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says

Hello, I am exploring the TCLTK package under R and try to load and use additional TCL libraries (under Windows, with TCL8.3). For example : > addTclPath("C:/TCL/lib/bwidget1.5") > tclRequire("BWidget") <Tcl> 1.5 Loading seems to work, but when I try to create a specific widget : # The main window appears correctly > top=tktoplevel() # Trying to insert a

[Environment: Win XP, R 2.10.1] I'm trying to install the packages JGR and iWidgets required by the extracat package to make the interactive plots in the package work. I've tried various things, but nothing seems to work. Here is my most recent attempt, followed by my sessionInfo(). Does anyone have any suggestions how to make this work? > > library(extracat) Loading

I would like to use a tclArray: mytkarray <- tclArray() as the variable for a table: table1 <- tkwidget(f1, 'table', variable= mytkarray) but if I include character strings with embedded spaces, I get braces appearing in the table. I can remove them using a non-R tclarray, (the difference between the first example of http://www.sciviews.org/_rgui/tcltk/Tktable.html and

Hi everyone, I wonder if anybody observed the crash of the tkfilefind demo. I looked into the code and it seems to crash executing dirtree<-tkwidget(base, "hierarchy_dir", root=path, showparent="Parent", showfiles=1, showall=all.names,

Tracing down some things to add in validators and I''ve run across something that kinda bothers me... In order to implement validators you have to override the clone method. The directors seems to be set up to specifically handle this situation. However, whenever C++ calls back to the object''s methods the swig_get_up function is returning false. It seems like swig_up

Thanks Peter, I've started a new R session (in Windows) and managed to get both ways working now : ### THIS WORKS !!! ### library(tcltk) tclRequire("IWidgets") tt<-tktoplevel() combo <- tkwidget(tt,"iwidgets::combobox") tkpack(combo) ### AND THIS WORKS TOO !!! ### tt<-tktoplevel() win <- .Tk.subwin(tt)
