How does one define PDFs as yet undefined in R, such as the ex- gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF would then be the convolution of an exponential PDF, dexp(), and a normal, dnorm(). Kindly cc me in your reply to r-help.

Dear R-listers, Can someone suggest a method for generating a finite Bernoulli sequence that is likely to have a given point-biserial correlation with an existing Bernoulli sequence? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102 Gilmer Hall

Dear r-helpers, I downloaded http://popgen.unimaas.nl/~jlindsey/rcode/rmutil.tar (it was originally .tgz, but got unzipped by my browser).

Dear R-helpers, I would like the bands in an xYplot() to be gray without dark edges. I've tried playing around with col.bands, but that seems not to affect the edges, although changin col.fill does change the fill as I would expect. I would appreciate pointers. _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box

Dear r-helpers, After updating to R version 2.2.1, 2005-12-20, powerpc-apple- darwin7.9.0 (from binary), JGR wouldn't launch. I then deleted everything I could find related to JGR, and reinstalled it from the latest binary. Both R and JGR are installed in /Applications/ \~LocalApps/mathStat/. Advice on how to identify the source of the problem? My machine: Machine Name:

Dear r-helpers, When use latex() on a matrix, I set the option dcolumn = T. As a result, in front of each tabular I get \newcolumntype{.}{D{.}{.}{-1}} The LaTeX compiler complains about these multiple redeclarations. _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room

Dear R-helpers, I need to generate all the binary sequences of length n (here n = 8) that start with 1 and have no fewer than two of each digit, and are not cyclic permutations of each other. Here is what I have done: len <- 8 df <- as.data.frame(numeric(2^(len - 1)) %o% numeric(len)) require(partitions) for (i in 1:2^(len - 1)) df[i, ] <- binary(i, dim = len)[[1]] df <-

df1 <- data.frame(a = LETTERS[1:2], b = LETTERS[3:4], c = 1:2) I am looking for an idiom that swaps the elements of df$a and df$b when (e.g.) df$c == 2, resulting in df2 <- data.frame(a = LETTERS[c(1, 4)], b = LETTERS[c(3, 2)], c = 1:2) _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA

Dear R-helpers, I'm trying to selectively swap labels between two factors, depending on an indicator variable i. Can you point me to a solution, and perhaps how I could have found it? labels(fact1) is a character vector of r row numbers levels(fact1) is a character vector of the n < r unique levels How do I then get the character vector of length r of the levels of fact1? Once I have

Dear R-helpers, I wasn't able to find out how to override the alphabetical ordering of the rows and columns in a vcd::mosaic plot. I would like to have them each ordered by numerical values in a different column of the data frame that contains the contingency data. I would be most grateful for a pointer toward the solution.

Dear r-helpers, When I do an xYplot and display the result in a JavaGD() window, the font is sans-serif (presumably Helvetica). When I send the figure to a pdf, I get a serif font (presumably times). How do I insure that the font in the pdf is indeed the default sans serif? > sessionInfo() R version 2.4.1 (2006-12-18) i386-apple-darwin8.8.1 locale: C attached base packages: [1]
