Trouble installing Rcpp on AIX - missing "execinfo.h"
Greetings,
When I try "install.packages('Rcpp')" it fails when compiling api.cpp (line 39). This is Rcpp 0.11.3. I searched my filesystem, and indeed I do not have execinfo.h anywhere. After some effort, I got R build on AIX. Now I am trying to build the packages I need. Rcpp is crucial.
I first build R with the native IBM XL compilers, and Rcpp wouldn't build. That was

database table merging tips with R
I have not devoted time to setting up ROracle since binaries are not available and it seems to require some effort to compile (see http://cran.r-project.org/web/packages/ROracle/index.html). On the other hand, RODBC worked more or less magically once I set up the data sources.
What is your success using ROracle and why would it be preferable to RODBC ?

How to recursively build a binary tree with R script?
Greetings!
Can someone provide a simple script for a R function that recursively builds a binary tree. I am most familiar with C and pass by reference, but I think R is like Fortran and pass by value.

vectorizing sapply() code (Modified by Aaron J. Mackey)
[ Not sure why, but the first time I sent this it never seemed to go
through; apologies if you're seeing this twice ... ]
I have some fully functional code that I'm guessing can be done
better/quicker with some savvy R vector tricks; any help to make this
run a bit faster would be greatly appreciated; I'm particularly stuck
on how to calculate using "row-wise" vectors

Using pipe for input data
Hi.
I have asked this question before and Aaron J. Mackey and Tony Plate gave me
some great insight but I still can't figure out how to do what I am trying
to accomplish. So let me ask again...
What I am trying to do is to make R read data from pipe (stdin).
Say I have following files on my directory

ignorepat doesn't work
Hi
in order to keep the dial tone after pressing 9 for 'outside line' I
have this in my extensions.conf
[localpstn]
ignorepat => 9
exten => _9[123456789]XXXXXXX,1,Dial,${PSTN}/${EXTEN:1}
exten => _9[123456789]XXXXXXX,2,Congestion
this is properly included in the handsets' context but the dial tone
disappears after pressing 9.
am I missing something?
thanks in advance

testing differences between slope differences with lme
hello
i have a mixed effect model which gives slope and intercept terms for 6
groups (diagnosis (3 levels) by risk group(2 levels)). the fixed part of
the model is --
brain volume ~ Diagnosis + Risk Group + (Risk Group * age : Diagnosis) - 1
thus allowing risk group age/slope terms to vary within diagnosis and
omitting a nonsignificant diagnosis by risk group intercept (age was
centered)

appreciated) -Aaron

How to plot error bars
I'm a newcomer to R. I can't seem to find any documentation how to add
error bars to points in scatter plots. I guess I could plot the points,
then compute and plot line segments in the X and/or Y directions to
represent the errors?

Dependency-aware scripting tools for R
There are numerous tools like scons, make, ruffus, ant, rake, etc.
that can be used to build complex pipelines based on task
dependencies. These tools are written in a variety of languages, but
I have not seen such a thing for R. Is anyone aware of a package
available? The goal is to be able to develop robust bioinformatic
pipelines driven by scripts written in R.
Thanks,

enabling reproducible research & R package management & install.package.version & BiocLite
Hi,
In support of reproducible research at my Institute, I seek an approach to re-creating the R environments in which an analysis has been conducted.
By which I mean, the exact version of R and the exact version of all packages used in a particular R session.
I am seeking comments/criticism of this as a goal, and of the following outline of an approach:

reading a "sparse" matrix into R
I have a 47k x 47k adjacency matrix that is very sparse (at most 30
entries per row); my textual representation therefore is simply an
adjacency list of connections between nodes for each row, e.g.
node connections
A B C D E
B A C D
C A E
D A
E A F
F E
G

I'd like to import this into a dataframe of node/connection
(character/vector-of-characters) pairs. I've experimented with

Simple R server for SQL Server?
I have a big SQL Server application that needs some help from R, and this R needs to load a large workspace in order to service the database request. I'd like to keep an R process running continually because loading the workspace takes about 1 minute. The data in the workspace doesn't change very often.
Rserve doesn't seem to align with my needs - I don't want a new workspace with

Event-triggered change in value with a time-delay
Hello,
I am solving a set of ODEs using deSolve and have run into a problem I
would appreciate some advice on. One of the parameters (m) in the ODEs
changes between two states when one of the variables (D) crosses a
threshold (D_T) for the first time in either direction. Additionally, when
the variable crosses the threshold (either by increasing or decreasing),
there is a time delay (delay)

embedding R?
My apologies if this is a FAQ, I searched the mailing list archives before
posting.
Background: I am a long time user of SPlus, and a recent user of R. My
work normally involves converting the raw output of something interesting
into data to be analyzed in S/R, for which I use Perl extensively. I then
import the data into S/R, perform the analyses I need, dumping the values
into a new file,
