color of plot axes involving POSIX types
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",

finding the colour at a point
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 ...

points on a sphere
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

Windows OS, R and unicode
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

if ... problem with compound instructions
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

transition matrices
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

Goodness-of-fit test for gamma distribution?
Hi all, I am wondering if anyone has written (or knows of) a function that will conduct a goodness-of-fit test for a gamma distribution. I am especially interested in test statistics have some asymptotic parametric distribution that is independent of sample size or values of fitted parameters (e.g., a chi-squared distribution with some fixed df), because I want to fit gamma distributions to

Question: nonlinear covariate terms in spatial regression
Hi all, I am trying to model (continuous) spatial variation in a response variable as a function of one or more of several explanatory variables. I am principally interested in obtaining some measure of the relative "importance" of the explanatory variables. I have found several R libraries that are tailored to this sort of problem (geoR, geoRglm, gstat, etc.); however, as near

.Random.seed is double
Hi I am experiencing a problem with the random number generator. When I call any function that involve RNG such as "runif" or "sample" I get this error: .Random.seed is not an integer vector but of type 'double' I can't coerce the random seed and it's recommended not to alter it anyway. Can anybody help me? Thanks and kind regards, Piero Visconti, PhD

(Slight) calculation discrepancy in escalc (metafor package)
Hello, I recently started using the metafor package (version 1.6-0) in R (2.15.1, 64-bit Windows 7) and noticed that I was getting slightly different values when I manually calculated the standardized mean difference versus what escalc was giving me. Here''s a very simple example: escalc(measure="SMD", m1i=5,m2i=10,n1i=5,n2i=5,sd1i=1,sd2i=2,vtype="LS") The result

using the sink() function in a for-look
hi all, i wanted to use the sink function to sequentially output regression summaries within a for-loop. i must have something wrong somewhere (or be using the sink function incorrectly), but can anyone help? the code I am using is: where data.x is a data.frame of independents, and data.y is a data.frame of dependents. > for (i in 1:length(data.y)){ > taxa.i <- names(data.y[i])

Naive knn question
Dear list, I have two dissimilarity matrices, one for a training data set which I then clustered using PAM. The second is a diss matrix for a validation data set (an independent field sample). I have been trying to use knn to distinguish distances between the validation data set and the 6 mediods of the training data defined by using PAM. I continue to get error messages in regards to either the

.Random.seed(0) is not a valid Normal type
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);

Paid support for R?
Dear R users, Sorry if this has been discussed before. I was recently looking at the MySQL site and saw that they offer various levels of paid support. The support options range from basic email support (USD200) through to extensive telephone support from the development team (USD10000). These are annual prices. This is something I would be happy to see available with R (maybe it is?). My
