Hi, I've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to

Hello, On Mac OS X, certain Aqua/Quartz UI functionality requires an application to be launched from within an app bundle, or (alternatively) requires a Carbon application with a resource fork. Playing with the wxWidgets distribution, I discovered that it is quite easy and transparent to make such a Carbon app from (I guess) any command line application. When applied to the R executable called

Hi again R People: This works fine: > library(tcltk) > a <- tclVar("4.5") > as.numeric(tclvalue(a)) [1] 4.5 > #But if you have: > b <- tclVar("pi") > as.numeric(tclvalue(b)) [1] NA Warning message: NAs introduced by coercion > Is anyone aware of a way around this, please? thanks, Erin -- Erin Hodgess Associate Professor Department of Computer

Hi All... In an attempt to read data from a file and feed it into a tcltk entry box, I've run into difficulties. The following hopefully describes my dilemma: tclvalue(x.var) <- 5 Works fine. tclvalue("x.var") <- 5 Does not work. [Error: Target of assignment expands to non-language object] tclvalue(eval(parse(text="x.var"))) <- 5 Also, does not work. Any
