Quick summary: - I got command line editing to work (thanks to all who responded to me), - but now my ``m'' key won't work in R (??!!??!!??), - and I can't find how to get command-line editing to use vi syntax. More detail: This posting consists of (1) a summary and thanks, and (2) some new questions. Summary and thanks: =================== I was having trouble

Hello, The history function doesn't seems to work when I am working with R. I have a .Rhistory file in my working directory and I have tried savehistory(file = ".Rhistory") or the command given in the history help : .Last <- function() if(interactive()) try(savehistory(".Rhistory")) and I get the same error message Error in

Hi, > history() gives Error in savehistory(file) : no history available to save although I can scroll throu history with C^uparrow an C^downarrow. How can I make history() work and/or show the current history in a file, so that I can choose from previous commands? The web did not throw up anything useful. TIA --Christian -- Christian W. Hoffmann, CH - 8915 Hausen am Albis,

Can anyone offer suggestion about getting readline to work on Solaris? (v1.5.1) When I use the up arrow or ctrl-p to try to repeat the last command my session just beeps. It appears that the .Rhistory file that should appear in my startup directory is not being created. Thanks! The screen shot below shows cled=TRUE and no .Rhistory file created: $ /apps/R-1.5.1/bin/R R : Copyright 2002, The

This question relates, at least vaguely, to recent postings from me concerning my attempts to build R-1.5.1 under Solaris 2.7. I've more or less given up on this, and I and a colleague are attempting to build R-1.5.1 on another machine in our Department, and are getting a ***different*** problem. Version details: platform sparc-sun-solaris2.9 arch sparc os solaris2.9

Hi all, I 've just reinstalled from the scratch my Windows 2000 (Italian version) on a formatted HD, because I like to clean the environment from time to time (say once a year). I'm currently using XEmacs-21.4.13 and R (rw1091) and Xemacs is configured as described in http://socserv.socsci.mcmaster.ca/jfox/Books/Companion/ESS/ess-xemacs.pdf The problem is that the command help.start()

A colleague of mine is trying to use nls() to effect an optimization, and is encountering a scoping problem. I should know how to solve it for him but .... well, I just don't. I also had a quick scrounge of the archives --- I know I've seen this topic addressed before --- but I couldn't track it down. So here's a toy example that demonstrates the problem: hhh <-

In checking over the solutions to some homework that I had assigned I observed the fact that in R (version 2.4.0) pnorm(-1.46) gives 0.07214504. The tables in the text book that I am using for the course give the probability as 0.0722. Fascinated, I scanned through 5 or 6 other text books (amongst the dozens of freebies from publishers that lurk on my shelf) and found that some agree with R

Hi, I'm trying to make a function which does a lot of computational work and visualization work. This won't be a problem, but as things can get a lot of computational time, I would like to print what is going on, but also instructions about what the user should do. A small example: fctn <- function(data.df){ cat("Calculating linear regression \n") data.lm <-

Hello, For verbose coding I'd like to do something like: > myfunction <- function(x){ > if (a){ > stop(paste(myfunction_name_here,"requires xyz!") > } Is that possible? Thanks for any hints, Joh

Hi wizards, I need to know how can I generate this numbers I have n numbers N1,N2 , Nn , but Nn = 1- sum(N1+N2+...+Nn-1) and sum(N1+N2+..Nn)=1 and N1,N2,..Nn with 0<N<1 . Does somebody know how to generate it ? Some distribution or algorithm. Thanks in advance. -- Web Page http://www.geocities.com/ricardo_rios_sv/index.html

Just now I again had occasion to want nested describe lists in a documentation file. I found that the bug which I reported on 18 October, 2001 still persists. I checked on the bug report at the R web page, and found that the notes say ``Not a problem in R 1.4.0 (2001-12-08)''. Well, it's still a problem for me --- using R 1.4.1.

Apologies for the off-topic question; as usual I'm trying to draw upon the unparalleled knowledge and sagacity of the r-help list. Please reply off-list if you can help me out. A collaborator of mine found a formula we need, on sheets which he had photocopied out of a book, some years ago. He cannot remember which book (he's getting to be as senile and forgetful as I am, poor bloke!).

I have just been bitten by a quirk in the behaviour of model.matrix. I used model.matrix inside a function, and passed to it a formula that was built elsewhere. The formula was of the form ``y ~ x + w + z''. Now, model.matrix cheerfully accepts formulae of this form, although it only ***needs*** the right hand side, i.e. ``~ x + w + z'' --- the ``y'' can be dropped (but

I'm experiencing a new and annoying phenomenon which seems to consist of an unfortunate interaction between R-1.7.0 and netscape version 7. When I invoke help.start(), a netscape window duly appears with the browser pointed at the file .../R/doc/html/index.html as one would hope and expect. However if I then ask for help on a function, e.g. > help(glm) the help does NOT get displayed

Hi, I am facing the problem that I want to plot a histogram chart set freq to true and overlay with normal or weibull or exponential distribution curve. The sample code is shown as below: >samp<-c(-8.2262,-8.2262,-8.2262,-8.20209,-8.09294,-8.07321,-8.07321, -8.07321,-8.07175,-8.04948,-8.04948,-8.04948,-8.03848,-8.03848,

I've built R functions to ``effect'' a particular distribution, and would like to find out if that distribution is already ``known'' by an existing name. (I.e. suppose it were called the ``Melvin'' distribution --- I've built dmelvin, pmelvin, qmelvin, and rmelvin as it were, but I need a real name to substitute for melvin.) The distribution is really just a toy
