similar to: is there a formatted output in R?

hi, I use R - 2.15(32bit), and want to make a code to clear a console. Actually, I used to run following code to do that but after update the version of R from 2.14 to 2.15, it doesn't work. cls <- function (t) { require(RDCOMClient) wsh <- COMCreate("Wscript.Shell") wsh$SendKeys("\f") invisible(wsh) } cls() or cls <-

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.

In response to a few private e-mails, here a summary of using Delphi, R-DCOM and R 2.2.0 1) As Earl Glynn noted ( http://finzi.psych.upenn.edu/R/Rhelp02a/archive/50705.html ), there were a few paths specific to my installation in http://www.menne-biomed.de/download/RDComDelphi.zip leading to path errors on compilation. Hopefully, this has been corrected in the new zip file. 2) Always check if

Is there a function in R for doing Greenhouse-Geiser correction in ANOVA models? Is it already available in the aov function? How do we use it? Best, Darren [[alternative HTML version deleted]]

Hello. Some months age an e-mail was posted in which a comparison between Glimmix and glm was discussed. I have not been able to find that e-mail on the R archive. Does anyone recall the date of the above e-mail?

# Dear list, # I am an R-beginner and # spent the last days looking for a method to insert tables produced # with R into a word document. I thought about SPPS: copy a table from # an SPO-file and paste it into a word document # (if needed do some formatting with that table). # Annother idea was, to produce a TEX-file, # insert it and make it a word-table. # I found the following libraries, which

Hi, I have a nicely printed table of results generated by R's > print(myresult) where myresult is a "data frame". I am trying to put this table into a powerpoint slide for presentation without re-typing and re-formating, i.e., present it as it is in the R window. This saves time when there are a lot of tables to be presented. I tried > sink("myresult.txt") >

Hi all I have a question regarding differences in the way gregpexr works in R 2.3.0 and R 2.4.0. In R 2.3.0, this is what happens: > gregexpr(" [a-z] [a-z] ", " a b c d e f ", perl=T) [[1]] [1] 1 3 5 7 9 attr(,"match.length") [1] 5 5 5 5 5 ... while in R 2.4.0, this is what happens: > gregexpr(" [a-z] [a-z] ", " a b c d e f ", perl=T)

Hello- It has been several years since anyone has asked, so i am asking again- has anyone created a routine to estimate confidence intervals for predictions from nls models (ala Bates and Watts 1988)? Thanks - Alice Shelly [[alternative HTML version deleted]]

Hello: Could anyone point me to a nice example where someone has created methods for "[" on a user defined Class? I looked at the package Matrix but that was a little daunting. I'm looking for someone a little more introductory. I've tried to search the help section and the web but its difficult since "[" isn't searchable. Thanks in advance! Greg [[alternative

Hello everyone, I'm working on a package using S4 classes and methods and I ran into the following "problem" when I tried to create an "apply" method for objects of one of my new classes. I've found a way around the problem but I wonder if I did not paint myself into the corner. I'd like your opinion about that. So I have an object "myObj" of class

This below is not solvable with uniroot to find "a": fn=function(a){ b=(0.7/a)-a (1/(a+b+1))-0.0025 } uniroot(fn,c(-500,500)) gives "Error in uniroot(fn, c(-500, 500)) : f() values at end points not of opposite sign" I read R-help posts and someone wrote a function: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/92407.html but it is not very precise. Is there any

Inspired by the functions that Barry Rawlingson and Dave Forrest posted for searching Rwiki and R-help archive, I've made up a function that does the search on Prof. Baron's site (Thanks to Prof. Baron's help on setting up the query string!): RSiteSearch <- function(string, restrict="Rhelp", format="long", sortby="score",

Hey everyone, I know that I can call 'R' from other scripts, and that I can make command calls from 'R' (e.g., using system() ). But how can I get 'R' to RETURN values to the script that called it. E.g., I would like to be able to do something like the following (as a simpler example) from a bash script: #!/bin/bash myTest=echo /usr/local/bin/R --no-restore

Suppose I have the following data: y x id 44 0 104 48 58 104 48 55 204 47 105 204 41 275 206 18 67 209 ....... I fit the model >fit=lme(y~x+I(x^2),random=~1|id) Now I want to make a prediction plot: >time=seq(0,300,len=100) >plot(predict(fit,data.frame(x=time),level=0)) Very fine. It gives me the prediction curve based on the model. My further request is to make a confidence bands

Hi Ezra, Thanks for the great work on BackgrounDRb. I have come across a couple of problems. 1. I wanted to define a simple class in the worker file to wrap up and pass back some data to my controller. It seems that if I create the class either inside or outside of my worker class (in the same file) it gets wrapper by a DRb::DRbUknown object and therefore cannot be accessed from my controller.

hie all i am trying to carry out a categorical data analysis but my problem is that when in i use the chi squared test some of my expected values are less than 5. is there a test that can handle this situation. the data is not a 2*2 table. its more from the social sciences where you have from strongly agree to strongly disagree. i know i can collapse vthe tables but there is a loss of

Hello useRs and helpRs, Some time ago, in a gallaxy far away (here is the thread : http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we discussed about a graph gallery showing the power of R in that domain. I did some work around that, and there is a (pretty advanced) draft here : http://addictedtor.free.fr/graphiques/displayGallery.php For instance, there are some of my graphs,
