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

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

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 #####

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,

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),

"user units" in plotrix
hi all - i'm having some difficulty figuring out how to convert
between "user units" (which i can't find a definition for in the
plotrix package) and either (a) device units (e.g. inches with PDFs)
or (b) user coordinates along any particular axis.
as an example, suppose i set up a PDF device with inches, the device
has both outer and inner magins, and the plot region has

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).

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

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

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

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

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

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

smbclient sending command to windows servers
I once used smbclient (or something in the smb suite) to send a command to
windows and reset my windows password.
I can't recall how I did it though (over a year ago).
What I would really like to do is use smb to send a command to a windows
machine that would run a script (shutting down Interwoven)
and then back up all the Interwoven files using rsync. The RSYNC portion
is easy since I

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

fitting a glm with matrix of responses

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.

How can convert user expired days in human readable ?
Hello all,
On my system, some users have expire day user settings. I write a
(python) script
then parse the: 7.th selection in the master.passwd
blabla:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:1064005200:xxxx:xxxx:xxxx:xxxx
How can I conver the number like 1064005200 to human readable date format ?
Or, there is a way to collect the information from a command interactively ?
