Hi all, So I've started working on this and I ran into something that I didn't know, namely that for x a multi-dimensional (2+) array, head(x) and tail(x) ignore dimension completely, treat x as an atomic vector, and return an (unclassed) atomic vector: > x = array(100, c(4, 5, 5)) > dim(x) [1] 4 5 5 > head(x, 1) [1] 100 > class(head(x)) [1] "numeric" (For a

Hi, Given that cdplot() is used to produce the conditional density of a categorical y along a numerical x, it seems natural that it could be used with a date or time x (such as 'POSIXct'). Is this desirable? If so, I've created a patch that would allow this, by coercing the POSIXct x variable to produce the density, but use the original POSIXct x to draw the x axis. Index:

Respected All, I hope you are enjoying good health, I am tring to write a program in R but could not be very sucessful. My program draws random sample form bivariate normal distribution and then compute a variable PIJ. For certian samples some entries of variable PIJ is apearing as negative, which result in negative variance estimator. I want to introduce a loop in my program that verify the each

hello R: we have a two-parameter IRT simulation code. The goal is to generate a response matrix.But the "for" part doesn't run. we don't know what is wrong with it. Thanks so much~~~ I <- 10 J <- 5 response <- matrix(0, 10, 5) pij <- function(a,b,theta) { a <- rnorm(J, 0.8, 0.04) a b <- rnorm(J, 0, 1) b theta <- rnorm(I, 0,1) theta for( i in 1:I ) { for(

Respected All, I am writing a program in R and facing some problem with applying "if statment". Program first draw random numbers from bivariate normal distribution then compute variable say Pi and Pij from that sample and then further computation ..... ..... ..... In some samples Pij is appearing with negitive sign and ultimately resulted in an negative variance estimator.

I have a math (and maybe an R) question. I want to find equilibrium population density values for a system of linear population growth equations (e.g., Pimm and Lawton 1977). The eventual goal is to perform stability analysis. I can find the partial differential equations for the Jacobian matrix, but I get stuck trying finding the equilibriuym pop densities (X*). Here is the (incorrect?) R code

Hi Has anybody done THD or THD-N measurements with the CELT Codec (bext would be on various bit rates) If someone could share results for Mono at 64kBit and Stereo at 128 and 196kBit it would be great. thank you very much Jochen -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Making lots of headway today. One of my major problems with wine-20041019 was solved by switching to non-managed mode. Now the program that would previously only work under wine-20040505 is working perfectly (AFAICT) under wine-20041019. When installing another program from the same company (Native INstruments) I start running into some sort of bail out, I guess, where Wine starts using

Hello, I want to solve a nonlinear 3SLS problem with "nlsystemfit()". The equations are of the form y_it = f_i(x,t,theta) The functions f_i(.) have to be formulated as R-functions. When invoking "nlsystemfit()" I get the error Error in deriv.formula(eqns[[i]], names(parmnames)) : Function 'f1' is not in the derivatives table

As it turns out, on cards that actually have CRTCs on them we're already calling drm_kms_helper_poll_enable(drm_dev) from nouveau_display_resume() before we call it in nouveau_pmops_runtime_resume(). This leads us to accidentally trying to enable polling twice, which results in a potential deadlock between the RPM locks and drm_dev->mode_config.mutex if we end up trying to enable polling

Hello, Is there a possibility of setting parameter constraints in nls.lm() ? The documentation does not say anything on that explicitly. In order to achieve the same effect, the criterion function could be penalized outside the valid domain. Is that a correct procedure? Kind regards, Kilian [[alternative HTML version deleted]]

Is there a way to use R as a client server application? Whitch means: 1. install R on a server (running as a service) 2. from client send R-scripts through IDE/Editor (TINN-R) to "R-server" 3. receive R-output on client All the Best Kilian Schwab

Hello. I try to compute a "White-corrected" ANOVA. Therefore I use the command "Anova" implemented in the car()-package): Anova(modelname, white.adjust="hc3") and receive the error message: "Fehler in SS[i] <- SS.term(names[i]) : nichts zu ersetzen" (German) "Error in SS[i] <- SS.term(names[i]) : nothing to replace" (probably being the

Hi I am trying to evaluate the quality of the CELT codec by using the 0.8.0 testcelt tool to encode and decode the input. I want to test different bitrates and selected the below parameters for 64, 96, 128, 196, 256kB: ./celt-0.8.0/libcelt/testcelt.exe 44100 2 256 46 $1.sw $1-64kb.sw ./celt-0.8.0/libcelt/testcelt.exe 44100 2 192 46 $1.sw $1-96kb.sw ./celt-0.8.0/libcelt/testcelt.exe 44100 2 128

Hi, does anyone have small programms in C, one to encode and one to decode with celt, that I could use for a fpga chip softcore? greets yon -------------- next part -------------- An HTML attachment was scrubbed...

As any of you using version 1.6 of Lustre knows, Lustre servers can now be started simply my mounting the devices it is using. Even an /etc/fstab entry can be used if you can have the mount delayed until the network is started. Given this change, you have also notices that we have eliminated the initscript for Lustre that used to exist for releases prior to 1.6. I''d like to take a
