Custom type
Hi.
I have a small problem with the custom type I am working on. I define
method ''evaluate'' which is called after all data is been collected. Here
it is:
module Puppet
newtype(:test) do
newparam(:name) do
end
newparam(:listen) do
defaultto "silent"
end
def evaluate
puts "evaluating..."
return super.evaluate

Evaluation of defaults in functions
Hello,
and sorry if this is already explained somewhere. I couldn't find anything.
R (2.3.1, Windows) seems to perform some kind of lazy evaluation when
evaluating defaults in function calls that, at least for me, leads to
unexpected results. Consider the following, seemingly equivalent functions:
> foo1 <- function(x, y=x) {
+ x <- 0
+ y
+ }
> foo1(1)
[1] 0
> foo2

Parallel R expression evaluations
Hi all,
I am using R-3.0.1 under Linux platform to embed R into my C++ code.
I am facing an error while executing more than 1 R-expressions parallelly.
I am executing round(X) and abs(X) parallelly on a set of 50 input rows
which resulted in segmentation fault after getting the following errors.

infinite recursion during package installation with methods, setAs
I ran into a problem recently trying to update a package which uses S4
methods using a recent beta of R. I think I can reproduce it with a
simple example. I have package called `testpkg' in directory testpkg/.
In the R/ subdirectory of testpkg/ I have a file called testpkg.R which
contains the following two lines:

Understanding eval
After many hours of debugging code, I came to the conclusion that I
have a fundamental misunderstanding regarding eval, and hope that
someone here can explain to me, why the following code acts as it does:
foo <- function(expr) {
eval(substitute(expr), envir=list(a=5), enclos=parent.frame())
}
bar <- function(er) {
foo(er)
}
> foo(a)

Coping with non-standard evaluation in R program analysis
Hello R experts,
I plan to develop a tool for dynamic analysis of R programs. I would like to trace function calls at runtime, capturing argument and return values. Following a suggestion made some time ago on this list, my high-level implementation strategy is to rewrite the AST, augmenting call expressions with pre-call and post-call shims to capture the arguments and return value,

The stages of standard function evaluation
Dear R Help folks --
I have been trying to put together a list of the steps or stages of R
function evaluation, with particular focus on those that have "standard" or
"nonstandard" forms. This is both for my own edification and also because I
am thinking of joining the world of R bloggers and have been trying to put
together some draft posting that might be useful. I seem to

avoiding a needless function evaluation in optimize() (PR#9523)
Full_Name: Jelle Goeman
Version: 2.4.0
OS: windows XP
Submission from: (NULL) (145.88.209.33)
Hi,
I like to use optimize() to optimize functions whose evaluation is costly in
terms of computation time. The Brent algorithm which is implemented in optimize
was designed to optimize a function with as few function evaluations as
possible. Therefore it bothers me that optimize() always evaluates

delayedAssign changing values
I'm not sure if this is a known peculiarity or a bug, but I stumbled across what I think is very odd behavior from delayedAssign. In the below example x switches values the first two times it is evaluated.
> delayedAssign("x", {x <- 2; x+3})
> x==x
[1] FALSE
> delayedAssign("x", {x <- 2; x+3})
> x

send_files failed to open filename ...
Hi everybody,
I'm mirroring some websites with rsync (daemon on the source), and I
noticed in the destination host some error messages 'send_files failed
to open filenames',
Actually, the concerned files are deleted on the source host, but I
would like to ask :
* why does rsync say these (in which phase) ?
* is these messages harmful or not ?

Weighting Schemes: Evaluation results
Hi all,
I have evaluated new weighting schemes along with their existing

Also, I have put together all the results files for easy access here:

and a README for getting started with xapian-evaluation module. Hopefully,
it might be of help to those who are new to

OpenSCAP failures to to OS version?
Hi - I?m running the OpenSCAP STIG profile on a new CentOS 7.1611 installation, and I get a few failures that look like this (output from openscap scan ?verbosity INFO). I suspect this is because the openscap module is not accepting CentOS 7 as RHEL 7 for rules purposes, despite an early check for "Community Enterprise Operating System 7? which succeeds.
