Hi, I'm trying to use Frank Harrell's Design:::ols function to do regression of y (numeric) on the interaction of two factors (x1 and x2), but Lapack throws an error: > library(Design) ... > load(url("http://www.csse.unimelb.edu.au/~gabraham/x")) > ols(y ~ x1 * x2, data=x) Error in chol2inv(fit$qr$qr) : 'size' cannot exceed nrow(x) = 20 > traceback()

Hello, I have a minimal example that shows a problem I'm having with parallel processing. library(parallel) mcmapply(function(x, y) { print("Running") Sys.sleep(10) }, as.list(1:10), as.list(10:1), mc.cores = 16, SIMPLIFY = FALSE) I see "Running" printed once every ten seconds. I read the documentation for mcmapply, but I don't understand why it wouldn't

The documentation states : An alternative parametrization (often used in ecology) is by the mean ?mu?, and ?size?, the dispersion parameter. However, this fails : > rnbinom(10, mu = 100, size = 0) [1] NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN Warning message: In rnbinom(10, mu = 100, size = 0) : NAs produced For dispersion set to 0, it should work like drawing from a Poisson distribution.

I have an S4 object class defined in a Bioconductor package which contains multiple slots, some of which are tibbles, whilst others are vectors. If I call slot(object, name) where 'name' is an slot that contains a vector, everything works as expected. However, when I call slot(object, name) where 'name' is an slot that contains a tibble I get the following warning: Warning

Buenos dias a todos, Me gustaria genear n muestras de una N(0,1) a determinados intervalos de tiempo. Asi por ejemplo, si el vector de tiempos es tiempos <- c(2, 4, 6) la primera columan debe generarse a los 2 segundos de ejecutado el script, la 2a columna a los 4 segundos y la ultima a los 6 segundos. Al final el tiempo total de ejecucion sera aproximadamente 12 segundos para completar

Hi, I want to put text on a plot containing something like: a = b^2 = <squared numeric value of b> using bquote. Example: mu = 5 plot(1:10,1:10) text(2,8, bquote(delta == mu^2)) # This works text(2.5,8, bquote(phantom(0) == .(mu^2))) # but is unpredictable text(2,8, bquote(delta == mu^2 == .(mu^2))) # This doesn't work The last text function returns the error:

Hi, R-help, (sessionInfo at the end) I'm trying to construct a function using bquote and running into a strange error message.

Hi, I need to plot the beta as the symbol, followed by the index 3 as the title of a graph. This code works> main= bquote(paste("Results for ", beta ==.(b1)) but I also need the index 3. I tried (simplified): >plot(x,y, main= bquote(paste("Results for ", beta, "3", ==.(b1)))) and a few other versions, but I can not get it to run properly. Any help would
