Hi, [some background] I have a dataset which describes a number of subjects doing a "scientific discovery". That is, they have to discover the rules underlying a particular domain. To do so, they have to set the levels of 5 variables which leads to a certain outcome. To identify what kind of "experiments" the subjects did, I want to combine these levels into one variable

After some fiddling around with the tapply command, I discovered that the factors (the INDEX argument) given to tapply must be specified in fastest-cycling first order. The following code shows how I discovered my error: (R version 1.2.1) -o-o-o-o-o- x <- as.data.frame(list(data=c(-9,0,3,1,-9,1,0,-9,0,3,1,-9,1,0), subj=c(rep(1,7),rep(2,7)),

Hi, first of all, I would like to take this opportunity to thank all of you "answer guys" for giving such detailed answers. I think I've learned about as much from all these answers as from the different S/R documents I've read so far. Anyway, I ran into a incompatability between S and R, that is, R does not know the "ticks=T/F" argument to functions like axis and

A couple of days ago I posted some elisp code that asks the user for confirmation before deleting a process buffer, e.g. the *R* buffer. However, this code was only evaluated if a buffer was killed by means of [C-x k]. The following code does not need to be bound to a particular key, it's internally called by kill-buffer. (Also works if buffer is deleted in other ways, e.g., [C-x C-c].)

Dear all, I've got a quite large dataframe (stor) with rows subject and rt (reaction time). I would like to split the reaction times per subject into 6 bins of equal size. Right now, I'm using the following code: bindata <- function(rt) { bindata <- rep(-1,length(rt)) binwidth <- length(rt)/6 bindata[order(rt)[(0*binwidth)+1:(1*binwidth)]] <- 1

I use AfterStep on Linux. I made an R.xpm file (attached) and put this icon in the "wharf". To invoke R I click on the R icon. I did not find an offical R.xpm, and so I am submitting this one for your collective consideration.... The idea behind the icon is that it looks like a scatterplot, which is "statistical". My main beefs with my R.xpm are that it doesn't have a

I would be very thankfull for such a solution, too .... "R.E. Darnell" wrote: > > Would introducing a "Are you sure?" question after kill the *R* ( or > whatever) buffer with a hasty C-x k be a popular default > "feature". How can I include this for my own use? > > Thanks > > Ross Darnell --

A couple of months ago, probably using an older version of R, R used to run the following code just fine: library("foreign") data.exp1 <- as.data.frame(read.spss("dataDef.sav")) Issuing the same commands now (after starting R using --vanilla), gives me the following behavior: > library("foreign") > x <- read.spss("dataDef.sav") Error

even for people who didn't like the outcome of the US elections this year, it must have been a joy to see all the nice (and not so nice) graphs that were shown. As an exercise, I recreated the map shown on the NY-Times website [ http://www.nytimes.com/packages/khtml/2004/11/03/politics/ 20041103_px_ELECT_GRAPHIC.html ] If you're interested,

Using netscape 4.03 (or 2.x or 3.x)/ R-0.62.1 with SPARC Solaris 2.4: when netscape is running for help, graphics in R quit with "Color allocation error". Closing netscape removes the problem. netscape does not interfere with other X11 imaging programs including ghostscript and ImageMagick except that it increases the contrast in my mailer windows slightly. (netscape does block

I'm trying to get Sweave running for automatic report generation, and it seems to run fine when just using verbatim output. However, I've ran into a problem with xtable. I would like to print the following matrix using xtable: > dim(counts) [1] 19 15 All columns are filled with real/integer numbers > 0 and < 1000. Just typing xtable(counts) gives correct LaTeX output, but

Thanks to Andy Liaw, Roger Peng, Thomas Lumley, Brian Ripley and Peter Dalgaard, all of whom addressed my questions or threads arising from them. The full messages were posted to the list so this is a brief summary: Andy Liaw explained the difference between lexical and dynamic scoping and the rationale behind the choice of lexical scoping for R. Roger Peng showed how to modify fnB. Brian

It is largely due superstition, but if you change f before calling split<-() you have split() and

Dear useRs, I have a complicated function to be optimized with optim(), and whose parameters are passed to another function within its evaluation. This function allows for the parameters to enter as arguments to various probability distribution functions. However, I am violating some scoping convention, as somewhere within the hierarchy of calls a variable is not visible. I will give a

Dear List members: I'm using R1.7.1 (Windows 2000) and having difficulty with scoping. I've studied the FAQ and on-line manuals and think I have identified the source of my difficulty, but cannot work out the solution. For the purposes of illustration. I have three functions as defined below: fnA <- function(my.x) { list(first=as.character(substitute(my.x)), second=sqrt(my.x)) }

Dear R-helpers: (this is part of a bigger program) the following fails as a function, but runs OK if we comment out the fnfn_ function() line. Any hint would be appreciated. -Yudi- R : Copyright 1998, The R Development Core Team Version 0.63.0 Beta (Nov 13, 1998) -- on WIndows3.11 fnfn _ function (m=10,n=10,spar=2) { fn _ function(u,v){ uc_ u-floor(m/2)-1 vc_ v-floor(n/2)-1

Thanks to Martin Maechler, Douglas Bates, Peter Dalgaard, and Hedderik van Rijn for pointing out the problem is with the color resource demands of the two applications and for their suggested possible solutions. A 24 bit monitor would be ideal and maybe someday I'll have the $$$ to upgrade. "netscape -install" works with the attendant flashing screen color changes from window to

Right now, we require the user to supply potential metacontext names in advance, without knowing what the server actually supports until after the connection or nbd_opt_info call is complete. But the NBD protocol also supports a client being able to query what contexts a server supports, including where a client asks with a prefix and the server replies back with all answers that match the

This commit implements some hairy C macros to simplify XML generation. Given the target XML: <cpu mode="host-passthrough"> <model fallback="allow"/> </cpu> The old code would have looked like this: XMLERROR (-1, xmlTextWriterStartElement (xo, BAD_CAST "cpu")); XMLERROR (-1, xmlTextWriterWriteAttribute (xo, BAD_CAST
