similar to: how to have tkchooseDirectory resize in windows?

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 <-

Hello, I am trying to setup a menu to open files and directories. I have the following code: opendir<-function() { dirname<<-tclvalue(tkchooseDirectory()) } openfile<-function() { filename<<-tclvalue(tkgetOpenFile()) } require(tcltk) t1<-tktoplevel() topMenu<-tkmenu(t1) tkconfigure(t1,menu=topMenu) plotMenu<-tkmenu(topMenu, tearoff=FALSE)

Sorry for the cross-post. Not sure where the problem is... A while back I posted an R function to R-help: cd <- function (dir = tclvalue(tkchooseDirectory()), saveOld = FALSE, loadNew = TRUE) { stopifnot(require(tcltk)) if (saveOld) save.image(compress = TRUE) setwd(dir) rm(list = ls(all = TRUE, envir = .GlobalEnv), envir = .GlobalEnv) if (loadNew &&

Dear R-help, Can anyone tell me if it's possible to call up the "directory chooser" (the one you get when you click on "File" -> "Change Dir...") in Rgui from the R command line? Seems like file.choose() can't be used to choose a directory. This is in R-1.8.1 on WinXPPro. Any help much appreciated! Andy

Hello, I'm newbie in R and I have a problem exporting a table with many columns to a dbf file. I found an error when I open the result DBF file on other software and also importing it on R again. Here a example snippet of the problem (on a GNU/Linux OS): http://pastebin.com/0SMJqqwb Is it a bug? Thank you, Nacho V [[alternative HTML version deleted]]

I hope others may find this useful. I use R in many different directories. By adding the following line to the .Rprofile file: utils:::setWindowTitle(paste("-",getwd())) the titlebar of each R instance shows the directory from which it was started. I have tested this with rterm.exe and rgui.exe under Windows and with RECENT versions of R only. ----- For changing directories

Does R have a dir.choose function? I can use file.choose like this as a kludge to get something like a dir.choose, but a real dir.choose would be better: cat("Select one of files in directory to process:\n") filename <- gsub("\\\\", "/", file.choose()) basepath <- dirname(filename) Windows provides a lower-level SHBrowseForFolder function to create such

Hello everyone, How can I specify in tcltk file browser the initial directory to "MyComputer" in Windows where Drives and Partition are accessible? And just a little question if anyone knows, is there a way to use the function choose.files under windows to select a directory? Thanks a lot for your help. Laetitia.

Hi all, I have written a R-script under Windows using choose.dir. Now, I have seen that this function is missing at MacOS. Does anybody know an alternative? Antje

To follow up on my previous question, suppose a user R session wants to unload one workspace and load another within an R session. Is the following the correct sequence? 1. save.image() to save the current workspace as .Rdata in the current working directory. 2. rm(list=ls()) to remove everything from the workspace. 3. setcwd("xxx") to set the new working directory. 4.

Is there anyway to have a function prompt the user for a working directory, equivalent to file.choose()? --Paul

I've rolled up R-1.6.1.tgz a short while ago. This is a minor upgrade, fixing an assortment of minor bugs, and one major one: 1.6.0 introduced a memory leak in deparsing, causing much trouble for people running simulations. You can get it from the developer site at http://cvs.r-project.org/pub/CRAN/src/base/R-1.6.1.tgz or wait for it to be mirrored at a CRAN site near you. Binaries for

I posted this to the comp.lang.tcl newsgroup, but it might relate to a possible bug in the Mingw32 cross-build environment under CentOS 6 (or EPEL).

Hello LLVMers (in particular, LLVMers interested in GSoC), Since people seem interested in GSoC project ideas, here is one that might not be totally obvious -- work on LLVM's testing infrastructure! :) I have been working hard on modernizing our nightly test performance monitoring software, but there is a lot more work to be done. As LLVM developers, we rely on this software for tracking

Hi List! May I tap into your combined common sense ? I have a legacy logging app that needs to be modernized. At the moment, Data is going to be stored in 5 tables, one table is going to contain more than 200 million and 2 others about 60 million rows. Mysql will be used, unless someone sees a major advantage in using something else (at the moment data is stored in a raw positioned file format,

Food for thought: If you have a codebase which can't use -fno-math-errno, because it relies on errno values from math functions, it may be a more effective long-term strategy to work on modernizing your codebase, eliminating the dependencies on errno, rather than going through the trouble of adding even more complexity to compilers to keep errno support limping along. Of course, whether this
