Dear R-devel friends: I'm back to bother you again about the conflict between mclapply and tcltk. I've been monitoring several packages that want to use mclapply to parallelize computations and need to figure out what should be done. It appears tcltk cannot be safely unloaded, so the best we can do is check for the presence of tcltk and stop if it is found before mclapply() is used. I

Hello, I spent a lot of a time on a weird bug, and I just managed to narrow it down. In parallel code (here with parallel::mclappy, but I got it doMC/multicore too), if the library(tcltk) is loaded, R hangs when trying to open a DB connection. I got the same behaviour on two different computers, one dual-core, and one 2 xeon quad-core. Here's the code: library(parallel) library(RSQLite)

Perhaps I'm being even thicker than usual, but I can't find the tcltk package on CRAN. There is a tcltk2 package, which says that it is a collection of supplements to tcltk, but I cannot see a just-plain tcltk anywhere. If I try to install tcltk2 (from the Linux command line, or using install.packages() in R) it complains that it needs tcltk. If I try to install tcltk using

Hi R-devel, tcltk devel, and sqldf devel, The transcript below shows how loading the tcl/tk library in under R causes subprocesses to ignore SIGPIPE. I am including the developer of the (wonderful) sqldf package since it requires tcltk and you might like to make this dependence optional to the user (at least until this is fixed in tcltk). Am I mistaken in calling this a 'bug'? Any

It seems that R is mostly distributed with the tcltk package but not always. Is there some reason for this inconsistency? It would be nice if one could count on those packages that are distributed on the Windows version of R being distributed on all other platforms too. -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com

Here's my little discussion example for a quadratic regression: http://pj.freefaculty.org/R/WorkingExamples/regression-quadratic-1.R Students press me to know the benefits of poly() over the more obvious regression formulas. I think I understand the theory on why poly() should be more numerically stable, but I'm having trouble writing down an example that proves the benefit of this. I

Hello, I am trying to write a tcltk based program that plots/manipulates xts/xoo time series objects. I have the code I used from ## http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tkrplot.html : ## require(quantmod) require(tcltk) library(tkrplot) Sys.setenv(TZ="GMT") getSymbols("^GSPC", from = "1960-01-01") Myhscale <- 2.5 # Horizontal scaling

Dear R Devel Some of our R users are still insisting we run R-2.15.3 because of difficulties with a package called OpenMX. It can't cooperate with new R, oh well. Other users need to run R-3.0.1. I'm looking for the most direct route to install both, and allow users to choose at runtime. In the cluster, things run faster if I install RPMs to each node, rather than putting R itself on

Hi, I am new to R, I need your help. I have been said to create a GUI in R, I started using Tcltk package which was very easy to learn and code, but i am unable to arrange the GUI's in proper order in the window they are always arranged one below the other, please can anyone help me in solving this problem, Is there any links which will help me solve this problem with

Greetings I want to take a fitted regression and replace all uses of a variable in a formula. For example, I'd like to take m1 <- lm(y ~ x1, data=dat) and replace x1 with something else, say x1c, so the formula would become m1 <- lm(y ~ x1c, data=dat) I have working code to finish that part of the problem, but it fails when the formula is more complicated. If the formula has log(x1)

On a x86 machine operating under Gentoo Linux, I'm having persistent difficulty in getting R version 2.6.1 (the latest available through Gentoo's portage system) to use tcltk.

Hello, Does anybody know how can i call a R function in a tcltk file? I made a tcltk file, but I need call functions in R. i.e: in R I can put .Tcl("tcltk statement"). There are a same command to call R in a tcltk file? I want to make a R Gui using tcltk language, do you recommend use a tcltk or a R pack tcltk and don't use tcltk language? Thanks for your attention.

I have had some comments on sqldf regarding its dependence on tcltk such as the second last sentence on this blog post: http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://www.wentrue.net/blog/%3Fp%3D453&prev=http://blogsearch.google.com/blogsearch%3Fhl%3Den%26ie%3DUTF-8%26q%3Dsqldf%26lr%3D%26sa%3DN%26start%3D10 sqldf does not directly use tcltk but it does use strapply in
