similar to: Compiling Tcl extension C Code for an R package

Dear R developers, I plan to upload a first version of my R package RnavGraph to the R CRAN server in a week or two. However I'm still struggling with an image resizing function written in C as a tcl extension. I did all my development in Ubuntu, and everything works fine in Ubuntu, however my attempts to compile this C function under Windows or OSX have all failed. I provide a minimal self

Dear R Community, I adapted the C-Code found at (http://wiki.tcl.tk/25685) implementing fast image resizing for Tk images for my R package. The C Code differs for tcl/tk version 8.4 and 8.5. I have the working code for both versions. How do I integrate this C-Code into my package so that R CMD INSTALL takes care of compiling the function correct for each OS and tcl version? (such that I can

Dear all, I am working on an R package intended for CRAN that requires Tcl version 8.6 because of the TclOO tcl extension and the -angle option for canvas text items. R for Windows currently still ships with Tcl 8.5. Does anyone have experience with linking R under Windows to a Tcl interpreter of version 8.6? When I link R 3.2.2 (installed from the binary on Windows 8) to a custom Tcl

Dear R-Community, I need the Img tk extension for my R package. It all works on my Ubuntu machine (libtk-img). However I experience a great deal of trouble when I try to install the package on OSX 10.5 or 10.6 (in fact I'm not able to do it). As I understand it, the ActiveTcl with it's teacup package manager do not have an effect on the the x11 tcl installation which R accesses. MacPorts

Dear R users, I have some troubles with dealing with tclObj objects. I try to explain it with a toy example: Say I define the following tcl procedure which just prints out each list element library(tcltk) .Tcl('proc test {myList} { foreach i $myList { puts stdout $i } }') and I call it with: > tcl('test',letters[1:5]) # Works as expected Now say I define

Dear R Community, I'm writing an R package with a lot of Tcl and Tk code. I use the Tcl wrapper functions provided by the tcltk package if possible. However I also define "pure" Tcl functions. I so far defined them with the .Tcl function, for example (in R): .Tcl('proc test {a b} { return [expr {sqrt(pow($a,2)+pow($b,2))}] }') so that I can use the procedures later on

Hello, a user of one of my packages has sent me the following problem that apparently appears when loading the tcltk package. I'm guessing something (Tcl/Tk? R open scripting framework?) is not installed correctly... can someone please confirm or correct my guess? The OS is Mac 10.6.5. Thanks, Peter This is what I get: > ~ joseoter$ r > R version 2.12.0 (2010-10-15) > Copyright

Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error : package 'tcltk' could not be loaded Ubuntu 9.10 I have both the 8.5 and 8.4 tcl and tk regular and dev libraries installed. I need both of these because some of my GIS software requires the 8.4 libraries. Should I remove the 8.5 libraries, or ... All help is greatly appreciated!

Hi List, Is it possible to tell R to use tcl/tk 8.5? My R package seems to depend on libtcl8.4.so. However, in Windows it seems to be possible to set TCL_LIBRARY and MY_TCLTK. Is there something similar possible in Linux? I have installed: $ rpm -q R R-2.3.1-1.fc5 $ locate libtcl8 /usr/lib/libtcl8.4.so /usr/local/lib/libtcl8.5.so

I discovered, while trying to set up Tcl bindings for Notmuch (https://notmuchmail.org/), which uses Xapian, that flintlock was not being locked (I had lost updates). I then found that opening a Xapian database for writing directly via the Xapian Tcl bindings also silently fails to lock flintlock. I have taken a copy of flint_lock.cc to play with, and I find that it locks the file when called
