When something gets printed by the "print.default" function, any extra attributes are printed without regard to their class attribute (if any). For example: > x <- 1:3 > attr( x, 'other') <- factor( c( 'cat', 'dog')) > attr( x, 'other') [1] cat dog Levels: cat dog > x [1] 1 2 3 attr(,"other") [1] 1 2 which is perhaps

Hi All, I would like to use anonymous cvs, but it appears not to be working (again?). There was a discussion back in Jan-Feb about whether to continue supporting it, but it seemed that Tony Rossini got it working and the discussion left off there. Did someone decide to disable it, or is it just not working properly? Here's the details: $ cvs -d

'getAnywhere' is not reporting methods when there are periods in the class name or the generic name (in R-devel). > getAnywhere( 'predict.loess') A single object matching 'predict.loess' was found It was found in the following places registered S3 method for predict from namespace modreg namespace:modreg with value <<...>> > getAnywhere(

Dear R users, I ran into this curious problem: > d <- rnorm(100) > d.density <- density(d) > sum( d.density$x * d.density$y) [1] 2.517502 Admittedly the method of computing the mass under the density curve at line 3 is crude. But 2.5 is pretty far from 1, the value it should be. I tried a few other dataset and got similar result. Am I missing something obvious? Or is the return

Thanks-- as Duncan Murdoch also noted, R_HISTFILE can be used to solve my problem, as below. BTW it's not easy to find out about R_HISTFILE in the help system or manuals, though, unless you already know it exists-- it only seems to be described under startup options, not things to do with history. However, Duncan's reply did hint at an inconsistency, in that savehistory() defaults to

A bit late for Santa, but on my wish-list nevertheless: is there any chance that "scan" and "readLines" could be extended to take a parameter "until" or "EOF.marker", which would be a character string that (if encountered while reading) would cause the reading to stop, just as if an end-of-file had been found? [But leaving a connection open, so that

As a user of only R, I don't use much of the potential of ESS and Emacs. Without entering a religious feud, is there any reason I should use XEmacs rather than my current GNU Emacs?

Dear list Can anyone suggest a simple way to abort execution like stop(...) does, but without issuing an "Error: ..." message? I don't want to set 'options( show.error.messages=TRUE)' because I want normal behaviour to resume after this particular stop. (Please reply personally as well as to the list, as I'm not subscribed to R-help) Thanks Mark -- Mark Bravington

Dear R-devel On my Windows 2000 machine, I can build R-patched but not R-devel (since at least 1/9/2004). An error message pops up during the execution of some R code during "make", as below. In terms of "make" etc., I am totally clueless (not being a user of either Linux or C) and just mechanically follow the instructions in the R documentation; hence I've got no idea

Dear group I use "restart" in part of my code, in a way that's not easily changed to "try". As I convert code from R1.5.0 to R1.6.1, I'm getting ugly messages; the help system says to contact r-devel, so here I am. This one's a bit complicated-- sorry! The context is inside a debugger (I have an R and S debugger that offers stand-alone code windows, line numbered

# r-bugs@r-project.org `predict' complains about new factor levels, even if the "new" levels are merely levels in the original that didn't occur in the original fit and were sensibly dropped, and that don't occur in the prediction data either. (At least if `drop.unused.levels' was set to TRUE, which the default.) test> scrunge.data.2_ data.frame( y=runif( 3),

Dear R experts, Sorry, I am resending this, since I have not received this mail myself for the past 5 hours. I saw a similar question dated July 2. But there is no answer to it. Does anybody have a solution to it? I am using window NT, and the R version is 1.5.1, the SJava package is the binary version SJavaWin_0.62-8.zip. Here are the error message: > library(SJava) > .JavaInit()

There is a bug in `predict' whereby the order of variables sometimes gets re-arranged compared to the original fit, and then disaster results. Specifically, the 'variables' and 'predvars' attributes of a 'terms' object get out of synch. This only happens when the terms in the original formula get re-ordered during fitting: test> scrunge.data_ data.frame(

Hi Folks, I'm currently looking at missing data/imputation methods (including multiple imputation). S-Plus has a "missing data library". What similar resources are available within R? Or does one roll one's own? Best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding at nessie.mcc.ac.uk>

Hello everyone, Thanks to all who offered suggestions after my initial query to the list. I've been busy trying to absorb the docs as fast as possible, but this little thing has me stumped for the moment. I'm creating a random sample of 100 item and saving it to a vector named 'iq'. I'd like to create a second vector (iq_prime, say) by adding 20 to each element of the

Dear list members, I've had helpful feedback from a number of people, several of whom experienced some problems getting my XEmacs/ESS configuration files for Windows to work properly. I will, of course, make changes based on this feedback, but the following information may be of use in the interim: (1) It's clear that my instructions and installation procedure were insufficiently
