vector S4 classes
...n Book, section 7.5 discusses new vector classes and uses
quaternions
as an example of a vector class that needs more than one number per
element.
I would like to define a new class that has a numeric vector and a
logical
vector of the same length that specifies whether the measurement was
accurate.
The following code does not behave as desired:
> setClass("thing",representation("vector",accurate="logical"))
[1] "thing"
> dput(x <- new("thing",1:10,accurate=rep(T,10)))
structure(c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), accurate = c(TRUE,...

Accurate seeking in a streamed file?
Hi,
Is it possible to accurately seek to a certain
position in an OGG file that is streamed off the
hard-drive/CD?
Or alternatively, is there a way to put a marker
somewhere in the OGG and seek to that?
Thanks for your help in advance.
Cheers,
J

LSODA not accurate when RK4 is; what's going on?
....
This can be used in computing the tail of the normal distribution.
(The actual solution is y(x) = exp(x^2/2) * Integral_x_inf {exp(-t^2/2) dt}
= Integral_0_inf {exp (-xt - t^2/2) dt}. For large x, y ~ 1/x, starting
around x~2.)
I'm testing both lsoda and rk4 from the package odesolve.
rk4 is accurate using step length 10^-2 and probably would be with even
larger steps.
lsoda is pretty accurate out to about x=4, then starts acting strangely. For
step length 10^-3, y suddenly starts to increase after 4, when it should be
strictly decreasing. For step length 10^-4, y instead turns down and start...

NLS results different from Excel -- Tricky fortunes nomination
...ould be
a good candidate for the R fortunes package -- except that it's about
Excel, not R! So I nominate it... but leave it to others to say
whether it's really "qualified" to be nominated.

"The idea that the Excel solver "has a good reputation for being fast
and accurate" does not withstand an examination of the Excel solver's
ability to solve the StRD nls test problems. ...
Excel solver does have the virtue that it will always produce an
answer, albeit one with zero accurate digits."

How 'accurate' is time sync on the samba server?
Just as the subject states, how close and accurate can time synchronization
be with Samba as a PDC and Windows Clients connecting to the PDC with net time?
I have setup a logon script, so when all Win2k clients connect to the PDC,
they will receive the logon script and use the PDC as their time server.
What I have noticed in my testing is that...

More accurate ODE solver?
Dear All,
I was using rk4 and lsoda to solve a ODE system. However, both of them gave
bad accurate solutions, especially compared with Matlab solver ODE45. For
example, ODE45 gave solutions that can go to a stable level (about 1.6) when
time goes to infinity, however, the solutions from lsoda are decreasing to
very very small (about 1e-130) numbers.
Does R have more accurate ODE solvers as ODE...

Philip,
Thanks for the clarification.
As far as I can tell, there is currently no way to preserve a full and accurate stack trace while utilizing most of LLVM’s optimization abilities.
The work on debug information may help you get the information you need, but I do not think we will provide information on stack frames that have been removed via inlining or tail call. Moreover, if at some point you also need the...

Extending the accuracy of exp(1) in R
Hi,
I want to use a more accurate value of exp(1). The value given by R is
2.718282. I want a value which has more than 15 decimal places. Can anyone let
me know how can I increase the accuracy level.
Actually there are some large multipliers of exp(1) in my whole expression, and
I want a more accurate result at the last step...

[LLVMdev] Preserving accurate stack traces with optimization?
Hi Philip,
Could you define what is an accurate stack trace for your project?
In other words, what do you mean by full and accurate stack frame?
Without this definition, this is difficult to give you any feedback. In particular, I do not see what it means when we use inlining.
E.g., what do you expect from code like this:
static void fct1(…) {...

Proposal: more accurate seq(from, to, length=n)
I just thought that returning a more accurate result was better and that
(1:10)/10
was an obvious way to calculate. It turned out that it was not that easy.
I found that calculation that I proposed previously was not accurate for
seq(-5, 5, length=101).
I then thought of
from + (0:(length.out - 1))/((length.out - 1)/(to - from)) ,
that is div...

We are investigating using LLVM as a JIT for a language which requires
the ability to generate an accurate stack trace from any arbitrary

Debug Locations for Optimized Code
I don't see how ASan and debuggers are different. It feels like both need reasonably accurate source location attribution for any instruction. ASan just happens to care more about loads and stores than interactive stepping debuggers.
Actually they are pretty different in their requirements.
ASan cares about *accurate* source location info for *specific* instructions, the ones that do some...
