Not an R question directly, but has anyone got a method for placing a moderately large number of (near) equi-spaced points on a sphere? I have a nasty feeling platonic solids are needed for exact solutions and I'm thinking of samplings involving around 200 - 1000 regularly-spaced points, Thanks, Richard Rowe Richard Rowe Senior Lecturer Department of Zoology and Tropical Ecology, James

I am attempting to plot frequency of occurrence against (calendar) time. As the output is to be produced as a Powerpoint picture on a dark background I wish to make the plot output yellow > par(col="yellow", col.axis="yellow", col.lab="yellow", col.main="yellow") > plot(t2, t1, ylim=c(0,40), main="Episynlestes run 2",

I think this was asked recently but I can't find the item. Is it possible to find the colour at a point on a graphics page? I want to estimate the area of a complex shape by colouring it then random sampling from an enclosing box ...

Hi, I used RODBC to import data from an Excel spreadsheet "*.xls", but some columns were returned as zeros. When I looked at these columns in Excel, I found that thery are results of formula calculations and not entry. My question is: Is there any parameter or command I need to use in order to overcome this problem? Thank you Ahmad Abu Hammour

Dear R-Developers and -Community, after compiling and installing R 1.2.2., I started 'demo(graphics)' for a test, and got: 'Error in rnorm(0): .Random.seed(0) is not a Normal type' Obviously .Random.seed was not initialized appropriately. Following the the documentation for '.Random.seed' [see below 'Examples'], this can be fixed rm(.Random.seed);

Hi, Thanks for showing me how to use RODBC and odbcConnect. Now works nicely. The question I've got now is: noms <- list.files(pattern=".DBF") # removing extension names: noms <- sapply(noms, function(x) as.character(strsplit(x,".DBF")) , USE.NAMES=F) for (i in 1:length(noms)) { s <- sqlFetch(bdades, noms[i]) # etc. } But it seems that sqlFetch()

Dear People, I have a data set of data x from a probability distribution, and I have a function, mydensity, of the pdf of that distribution. I'm asking for help in superimposing the histogram of x and the plot of mydensity. In the function below, I call truehist and curve, but these are plotted in different figures. I'd like them to be plotted on the same figure, and to use common

I would like to do some fairly basic stem-and-leaf displays in R. I am aware (I might even say painfully aware) of stem(base) and have tried it. That's why I'm hoping someone has a usable stem- and-leaf display for R so that I don't have to write my own. r-project.org > Search > R Site Search > "stem and leaf display" finds nothing. I also tried the mail archive

I've rolled up R-1.2.3.tgz a moment ago. This is mainly adds fixes to the Macintosh port, but it also has a number of bugfixes for all versions. You can get it from the developer site ftp://cvs.r-project.org/pub/CRAN/src/base/R-1.2.3.tgz or http://cvs.r-project.org/pub/CRAN/src/base/R-1.2.3.tgz or wait for it to be mirrored at a CRAN site near you within a day or two.

I am working with transition matrices of sequences of animal behaviours. What I would like to do is parse the original matrices, adjusting row/column order so that the matrix has its main values in blocks surrounding the diagonal. This would cause behaviours involved in functional groupings (e.g. grooming, resting, foraging etc) to appear as blocks. This can be done manually by applying

Guess what I have no clue what i am doing/ meant to do with R. i have just begun statistics for uni and all commands don't seem to work, they say syntax error, we are meant to put a hist.r in but ? please help, step by step, to use this program i would turn it on (it comes up rgui) is this wrong, have i put the wrong bit on it? Please help, I am so glad there is an R help Thankyou jill

I'm trying to use the biological female and male signs in R2.5.1 under Windows XP. I can access and insert these symbols using word-processors. In general these should be available as \u2640 and \u2642 but I can't make them happen in R using (say) text(5,5, "\u2640") message "invalid \uxxxx sequence" I've replaced Arial with Arial unicode MS in Rdevga and

I am having problems with the 'if' syntax. I have an n x 4 matrix, X say. The first two columns hold x, y values and I am attempting to fill the second two columns with the quadrant in which the datapoint (x, y) is and with the heading angle. So I have two problems 1) how to do this elegantly (at which I've failed as I can't seem to vectorize the problem) and 2) how to

Dear all, 1. How can I compute the intersecting area between 2 polygons ? 2. I have polygons with coordinates in decimal degrees (i.e. 13 deg 30 min = 13.5 decimal degrees). I want to compute their area and get the results in square meters or square kiometers. Can anyone give me a conversion coefficient or a pointer where I can find this information (sorry for this off topic question) ? Thanks

Hello R users, I'm using xyplot (lattice) to plot some data. Unfortunately, the text that goes into each strip is often too big to fit. For instance, one of the factors may be labelled "Satisfaction with waiting time" which is too wide to fit. If I use split.string() to wrap it onto two lines it is then too high to fit in the strip. I'd prefer to apply split.string on the

Based on a report to the Windows maintainers from Richard Rowe <Richard.Rowe@jcu.edu.au>: NEWS for 1.3.0 says o Exact p-values are available for the two-sided two-sample Kolmogorov-Smirnov test. I think the (new) p-values are computed but are backwards: > set.seed(123) > x <- rnorm(50) > y <- runif(50) > ks.test(x,y, exact=T)$p [1] 1 > 1 - ks.test(x,y,

I've prepared preliminary versions of two packages that I plan eventually to contribute to CRAN: car (for "Companion to Applied Regression") is a package that provides a variety of functions in support of linear and generalized linear models, including regression diagnostics (e.g., studentized residuals, hat-values, Cook's distances, dfbeta, dfbetas, added-variable plots,
