...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(TR...

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.

.... 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 sta...

...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." --- I also leave it to others to modify what is excerpted if a...

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 th...

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...

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 t...

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 st...

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(…)...

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...

Is there a known way to preserve a full and accurate stack trace while utilizing most of LLVM's optimization abilities? We are investigating using LLVM as a JIT for a language which requires the ability to generate an accurate stack trace from any arbitrary point(1) during the execution. I know that we can make this work by doing inlinin...

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 s...
