list of matrices --> array
i'm somehow embarrassed to even ask this, but is there any built-in method for doing this: my_list <- list() my_list[[1]] <- matrix(1:20, ncol = 5) my_list[[2]] <- matrix(20:1, ncol = 5) now, knowing that these matrices are identical in dimension, i'd like to unfold the list to a 2x4x5 (or some other permutation of the dim sizes) array. i know i can initialize the array, then

vectorized plotmath expressions via substitute()
hi all - i've seen versions of this question before, but none seem to get directly at my solving my (probably very simple) issue: i simply want to annotate the tick marks on an axis with (superscripted) 10^x notation, and tried this: axis(1, at = axTicks(1), as.expression(substitute(10^foo, list(foo = axTicks(1)))) thinking the as.expression/substitute would create the appropriate

wilcox.test p-value = 0
hi, folks, how have you gone about reporting a p-value from a test when the returned value from a test (in this case a rank-sum test) is numerically equal to 0 according to the machine? the next lowest value greater than zero that is distinct from zero on the machine is likely algorithm-dependent (the algorithm of the test itself), but without knowing the explicit steps of the algorithm

dimension-preserving matrix coersion
i've written a function to coerce a matrix (e.g. from numeric to logical), but i'd like to know if someone has a more elegant method for this: > m <- matrix(c(0, 1, 1, 0), ncol = 2) > m <- as.logical(m) > m [1] FALSE TRUE TRUE FALSE i'd like 'm' to still be a matrix with the original dimensions. in my function to do this, i coerce 'm' to a logical,

bootstrap vignette construction and package installation
hi all - i'm trying to 'R CMD build' a package, but i have what appears to be a bootstrapping problem: i've included a vignette in my package, with R code interwoven (and built using Sweave), but in this documentation i have a code line: > library(MyPackage) now, when trying to build a .tar.gz install-able version of my package in a clean state, i remove the original

aggregate(...) with multiple functions
hi all - i'm just wondering what sort of code people write to essentially performa an aggregate call, but with different functions being applied to the various columns. for example, if i have a data frame x and would like to marginalize by a factor f for the rows, but apply mean() to col1 and median() to col2. if i wanted to apply mean() to both columns, i would call: aggregate(x, list(f),

difficulty with R expressions in text/legend
hi, i'm trying to prepend some plain (i.e. unevalutated) text to a typographically evaluated R expression in a legend(...) call. here's a working legend(...) call that is close to what i'd like (where x and y are returned from an lm(...) call): legend("topleft", legend = c(bquote(R^2 == .(summary(x)$r.squared)), bquote(R^2 == .(summary(y)$r.squared))), fill =

advice on package devel with external libs
hi all - i'm working on an R package that makes use of my own shared library written in C. but i also am making use of another C-written library. (my package is for facilitating biological namespace translations via online (i.e. up-to-date) biological databases.) problem is, the library i'm using is not a standard library (i.e. i doubt it will be installed on most users' machines). i

proper use of reg.finalizer to close connections
Hi all, I have a question about finalizers... I have a package that manages state for a few connections, and I'd like to ensure that these connections are 'cleanly' closed upon either (i) R quitting or (ii) an unloading of the package. So, in a pared-down example package with a single R file, it looks something like: ##### BEGIN PACKAGE CODE ##### .CONNS <- new.env(parent =

source package build/installation with subdirectory-lib
hi all - i have a source package i'm writing that i'd like to be able to install with a special library that my R src files rely on. to be more precise, i have a normal R package directory structure (i.e. src/ R/ man/ DESCRIPTION NAMESPACE etc.). i also have another directory here called depPkg, and it has it's own configure file for the canonical './configure && make

several common sub-axes within multiple plot area
Dear List, I'd really appreciate tip's or code demonstrating how i can achieve some common axis labels integrated into a multiple plot. In my example (below), i'm trying to achieve: -a single "Results 1 (Int)" centered & btwn row 1 and row 2; -a single "Results 2 (Int)" centered & btwn row 2 and row 3; and, -a single "Results 3 (Int)" centered

common base functions stripping S3 class
Hi all --- this is less a specific question and more general regarding S3 classes. I've noticed that quite a few very common default implementations of generic functions (e.g. `unique`, `[`, `as.data.frame`) strip away class information. In some cases, it appears conditionals have been created to re-assign the class, but only for a few special types. For example, in `unique.default`, if the

single row/column-indexing on matrices
hi all - quick question: i have a matrix m, say nrow=5, ncol=4. in a function i'd like to retrieve certain rows or columns from m, but which rows/cols are not known ahead of time. the function should return a sub-matrix (i.e. still of class 'matrix'). when selecting a single column (or row), the indexing operation converts the object of class 'matrix' into a vector of

ESS (emacs speaks statistics) saving history
hi folks, i use ESS mode in emacs often to interact with R, and while i know how to save a session transcript, i'm wondering how to save just the history of the commands (i.e. identically to how R gives the history save option from its native CLI). if you use ESS with an R process, commands entered from a separate buffer and sent to the process do not get registered with the R history, and

fitting a glm with matrix of responses
hi all - quick question: i have a matrix 'y' of response values, with two explanatory variables 'x1' and 'x2'. tested values of 'x1' and 'x2' are sitting in two vectors 'x1' and 'x2'. i want to learn model parameters without "unrolling" the matrix of response values. example below: # some fake data for the example x1 <- 1:5 x2

specifying an unbalanced mixed-effects model for anova
hi all - i'm having trouble using lme to specify a mixed effects model. i'm pretty sure this is quite easy for the experienced anova-er, which i unfortunately am not. i have a data frame with the following columns: col 1 : "Score1" (this is a continuous numeric measure between 0 and 1) col 2 : "Score2" (another continuous numeric measure, this time bounded between 0

library.dynam
hi, i'm having some trouble getting a package to load a shared library object in .onLoad(...) i have a shared object file, say "mylib.so". if i start an R session, and via the CLI specify the actual library via: > dyn.load("mylib.so") everything works quite well (i.e. i can then follow with some .Call (...) methods) now, i'd like to include this shared library in

shared object location
hi all, i posted a question before about this, but i may have been too cryptic to understand. in short, there exists an R package that someone is writing. this package depends on a custom library (written in C,), compiled as a shared, and called by the package's functions via the .Call(...) method. we are testing out different code implementations of the compiled library functions, and thus

Centring titles for pairs of plots.
I would like to centre titles for pairs of plots in a 3-x-2 array. Each row of the array corresponds to a calendar year and I would like to have the year value centred between the two plots in the row, and just above their upper edges. I have attached an example in "demo.pdf" showing roughly what I want. I managed to produce the example using
