Could I suggest the following extension to plot.formula: plot(cbind(y1,y2) ~ x, ...) should plot (y1 against x) and (y2 against x) on the same plot. The default y axis limits would be determined by the range of c(y1,y2). This would be pretty handy sometimes, replacing 4 lines of code. The current plot.formula evaluates cbind(y1,y2), which is a matrix, so plot.formula looks for

Bug summary: glm() causes a segfault if the argument 'data' is a data frame with more than 16384 rows. Bug demonstration: -------input --------------- N <- 16400 df <- data.frame(x=runif(N, min=1,max=2),y=rpois(N, 2)) glm(y ~ x, family=poisson, data=df) ------ output --------------- *** caught segfault *** address (nil),

Sorry if this is a FAQ. Is there a good reason why a factor has to be a one-dimensional vector and cannot be a matrix? I want to construct matrices of categorical values. Vain attempts like matrix(factor(c(T,F,F,T), 2,2) yield a matrix of character strings representing the factor levels, not the levels themselves, while factor(matrix(c(T,F,F,T), 2,2)) converts the matrix to a

Hi, Sorry if this is already known... contour() sometimes draws contour lines that intersect. Is there a temporary fix? A dataset which causes problems is at http://www.maths.uwa.edu.au/~adrian/dumpdata.R If you try just source("dumpdata.R") image(huh) contour(huh) the 100 x 100 matrix 'huh' contains an hourglass-shaped region of values around 0.8. The contour plot

gReetings, I want to manipulate a formula object, containing the name "." so that "." is replaced by a desired (arbitrary) expression. What is a safe way to do this? Adrian Baddeley

Wise and merciful R-helpers: I want to equip a data frame with an attribute which specifies how to plot some of the columns. Up to now we have been doing this by giving the data frame a `formula' attribute, that can be passed to plot.formula. For example dat <- data.frame(x=1:100,y=runif(100),z=100:1) attr(dat, "plotme") <- (z ~ x) ...... ......

Dear R-helpers Are there any established R packages that include a C code generator -- that generates new C language files and compiles them? To be precise what I'm looking for is a process that takes text input in some format (it might be pseudocode, fragments of C code, etc) and creates a valid C language source file that can be compiled by R CMD COMPILE. Ideally the procedure should also

Hello, All: The vignette with the sos package used "upquote.sty", required for R Journal when it was published in 2009. Current CRAN policy disallows "upquote.sty", and I've so far not found a way to pass "R CMD check" with sos without upquote.sty. I changed sos.Rnw per an email exchange with Prof. Ripley without solving the problem; see below. The

Dear all, I am trying to install the R-2.0.0-1mdk.i586.rpm <http://cran.planetmirror.com/bin/linux/mandrake/10.0/R-2.0.0-1mdk.i586.rpm> file on mandrake 10.1. Since the file is, originally, meant for Mandrake 10.0, it is not surprising me that the installation does not work. The error message that I get can be translated in something like: "impossible to install since the info

I have found a strange scoping problem in Sweave. The following Rnw file doesn't produce the same output in Sweave as it does if I produce an R file using Stangle and execute that: \documentclass[12pt]{article} \begin{document} <<R>>= election <- data.frame(A=1:3, B=9:7, C=rep(0,3)) partytotal <- rep(0, ncol(election)) for (i in 1:ncol(election)) { partytotal[i] <-

Hi Everyone, >From windows 2K, machine I could see Samba server but I can't get its share. I tried to follow the instruction given at http://samba.planetmirror.com/samba/ftp/docs/Samba24Hc13.pdf to resolve the problem. nmblookup -U 127.0.0.1 _SAMBA_ and nmblookup -B 10.10.255.255 real-samba-server-name fails for me but nmblookup -U 127.0.0.1 real-samba-server-name

The question puzzled me at first, because of your use of "library". It looks as if the hdf5 r "package" utilises the "windows hdf5 library" binary. My reading is that you will have to compile the package yourself after you have downloaded the hdf windows dll from hdf.ncsa.uiuc.edu The instructions are in win.readme.txt of the package source which you can download at

A question about the inner workings of glm() and dpois(): Suppose I call glm(y ~ x, family=poisson, weights = w) where y contains NON-INTEGER (but still nonnegative) values. (a) Does glm() still correctly maximise the weighted Poisson loglikelihood ? (i.e. the function given by the same formal expression as the weighted loglikelihood of independent Poisson variables Y_i except that the

Hi Folks, For some time, we've been having some issues with our mirroring with rsync. The symptoms are a broken transfer, with the 'cryptic' error message: rsync: connection unexpectedly closed (1128806 bytes read so far) (the number of bytes changes). I've gone a number of hours searching with Google, and have heard a variety of things. Some messages say that they see this
