similar to: clear console

I?ve been using this routine for several years. I?m sorry, I don?t remember where I got it. It works as it should, viz. it blanks the R console. But it requires package rcom and now that requires rscproxy. cls <- function () { require(rcom) wsh <- comCreateObject("Wscript.Shell") comInvoke(wsh, "SendKeys", "\f") invisible(wsh) } > cls()

Greetings R-ians: Searching the Searchable Mail Archives I discovered that ctrl L will clear the Rgui screen, which is what I'd like to do from a print (or some similar) statement. Is there a mechanism to use the ctrl L clear-screen sequence in a script, or print statement? Thanks for your counsel. Charles Annis, P.E.

Hi,   I'm reading 100s of excel files and many of them contain links to external files (I hate that, but that aside). Every time such a file is opened, a menu pops up asking if I want to update the links. I never want to update the links. I used the macro recorder to see what code would be needed to suppress that message, but to no avail (I tried more variations, but one attempt is shown

Hi, I would like to some excel files with some worksheets. I tried this with the following R script: library(gdata) i<-1 rc<-0 while(rc != "try-error") { wksh<-try(read.xls("cluster-microarray-FW.xls",sheet=i,verbose=TRUE,perl="perl")) rc<-class(wksh) print(sprintf("------- i=%2d rc=%s ---------------",i,rc)) if (rc !=

Ok I need to run a .vbs for a program which I run in wine (diablo 2). Google says "VBS in Linux. It works fine running in WINE. You just have to install the Windows Script Host. And you may need to hand-register the COM DLLs in the WSH installer at the command line. Last I saw, WINE wasn't handling self-reg. DLLs." I downloaded WSH 5.6 and ran that in WINE. When it was done I

My question is when the object argument of NexthMethod be used? In the following example, weather object argument is used will not affects the result. ### foo=function(x) {UseMethod("foo")} foo.cls1=function(x) { x=x+1;class(x)<-"ncls" NextMethod() } foo.ncls=function(x) { cat("ncls\n") } foo.cls2=function(x) { cat("cls2\n");print(x) }

Is there such a thing as a Samba logoff script? I am currently using [NETLOGON] for logon scripts, but for the adding and removing of printers via WSH, I'd prefer to also remove these printers after I log off. ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | | Ryan Novosielski - Jr. UNIX Systems Admin |$&| |__| | | |__/ | \| _| | novosirj@umdnj.edu - 973/972.0922 (2-0922) \__/

Hello, Could anybody offer any advice about implementing a Kohonen self organizing map for categorical data? Specifically I am wondering if there are any pre-existent packages that can deal with categorical data and/or how one would compare the input vector of categoricals with the self organizing map nodes. Thanks in advance. George Chen ----- Original Message ----- From: r-help-request at

Hi, I have a requirement that, I should run WSH and WMI scripts in Linux environment in order to do some registry changes on a remote machine and start/stop/query windows services on a remote machine.

Hi, After some googling I've found that there's very little said about the possibility of using WMI from Wine. Has someone done any progress about it? I find this subject very important; if you feel interested here's why: One may think this is a somehow fanciful intention, after all WMI exists for the purpouse of administering Windows, and no doubt that's best done from

Dan/Park, What are your thoughts about implemented portion of the win32utils family that are written in ruby utilizing WIN32OLE. I have found myself writing decent amount of ruby code accessing the Windows Scripting Host (WSH) object models. I have a few scripts which could be added. I do not believe the functionality is currently available with win32utils: - map network drives -

Hi All, Is there a way (speak command/wsh script) that allows a win9x workstation that is logged into a samba domain server (running onlinux for example) to see from the workstation what owner a certain file or directory has? Under win2k the "dir /q" command does this adequately. And if this is possible, is it then possible for someone to change the ownership of a file to another

Dear R-List member, I have installed the new version of R on my PC (see system details below). I can start the RGui with http_proxy succesfully.

I am a pretty new Wine user. I am hoping to be able to run some pretty large VBScript applications on it, to avoid porting them to Perl when we retire a Windows machine. All of our VBScript runs as children of a WSH ".wsf" file, for example as follows. I can get a simple ".vbs" file to run fine, but when I try to run the same file inside of a simple ".wsf" wrapper,
