Lattice: combine the same strip?
Hello R helpers, I am producing a figure with dual strips, i.e., x~y | S1 + S2, where S1 and S2 are two strips. For example, in figure 2.1 at http://lmdvr.r-forge.r-project.org/figures/figures.html. In this case, I would like to combine the the top strip, since all three pictures in the same row have the same level based on the first strip. In other words, instead of | -- S11 -- | -- S11 -- |

Multivariate regression method
Hi Folks, Thanks to several people's suggestions and clarifications, I think I have implemented a function which computes the conditional mean and covariance matrix of a subset of the dimensions of an MV-normal variable, given the values on the other dimensions (these conditioning value can be presented as a matrix, to deal with several cases at once). The code is below, for anyone who would

Wide to long form conversion
I have some data 'myData' in wide form (attached at the end), and would like to convert it to long form. I wish to have five variables in the result: 1) Subj: factor 2) Group: between-subjects factor (2 levels: s / w) 3) Reference: within-subject factor (2 levels: Me / She) 4) F: within-subject factor (2 levels: F1 / F2) 5) J: within-subject factor (2 levels: J1 / J2) As this is the

finite mixture model (2-component Weibull): plotting Weibull components?
Dear Knowledgeable R Community Members, Please excuse my ignorance, I apologize in advance if this is an easy question, but I am a bit stumped and could use a little guidance. I have a finite mixture modeling problem -- for example, a 2-component Weibull mixture -- where the components have a large overlap, and I am trying to adapt the "mclust" package which concern to normal

[LLVMdev] Request for merge: GHC/ARM calling convention.
Hi Karel, I understand this patch has already been merged (to 3.0), so don't take my question as stopping the merge to head, I'm just making sure I got it right...

[ARM] Register pressure with -mthumb forces register reload before each call
Hi, Compiling attached test-case, which is reduced version of of uECC_shared_secret from tinycrypt library [1], with --target=arm-linux-gnueabi -march=armv6-m -Oz -S results in reloading of register holding function's address before every call to blx: ldr r3, .LCPI0_0 blx r3 mov r0, r6 mov r1, r5 mov r2, r4 ldr r3,

[ARM] Register pressure with -mthumb forces register reload before each call
If I'm understanding what's going on in this test correctly, what's happening is: * ARMTargetLowering::LowerCall prefers indirect calls when a function is called at least 3 times in minsize * In thumb 1 (without -fno-omit-frame-pointer) we have effectively only 3 callee-saved registers (r4-r6) * The function has three arguments, so those three plus the register we need to hold the

[ARM] Register pressure with -mthumb forces register reload before each call
Hi, I have attached WIP patch for adding foldMemoryOperand to Thumb1InstrInfo. For the following case: void f(int x, int y, int z) { void bar(int, int, int); bar(x, y, z); bar(x, z, y); bar(y, x, z); bar(y, y, x); } it calls foldMemoryOperand twice, and thus converts two calls from blx to bl. callMI->dump() shows the function name "bar" correctly, however in generated

Multiple hist(ograms) - One plot
Hello, I am trying to plot multiple histograms with the same scales, etc into one plot. The commands below produce a 3 page PDF with each histogram occupying the upper right quadrant. And use slightly different scales on the X and Y axes. > s21 <- dat[dat$sc_recov=="21",] > s21.ED <- subset(s21, select=(bbED)) > s31 <- all[all$sc_recov=="31",] > s31.ED

[LLVMdev] Request for merge: GHC/ARM calling convention.
Hello, first of all: one of the LLVM 3.0 new feature was a support for GHC specific calling convention on ARM platform. It looks like this support was merged just into 3.0 branch, specifically it appeared in 3.0 RC2. Anyway, I hope this is just a mistake or omission that such support was merged only into 3.0 and not also into HEAD. I've just found it by testing LLVM 3.1 with GHC 7.4.2 and

test for whether dataset comes from a known MVN
Dear all, I have a multivariate dataset containing 100,000 or more points. I want find the p-value for the dataset of points coming from a particular multivariate normal distribution With mean vector u Covariance matrix s2 So H0: points ~ MVN( u, s2) H1: points not ~ MVN( u, s2) How do I find the p-value in R? To me this is a likelihood ratio test problem. In H0 the parameters are

Error using function MVN in package MCLUST: Fortran symbol name not in DLL for package
Hi All, I need to fit a mutlivariate normal model to a dataset in order to obtain the mean and covariance parameters. I see that the MVN function in the MCLUST package can do this, however when I try to run even the simplest example provided in the documentation, as below, I get the following error: n <- 1000 set.seed(0) x <- rnorm(n, mean = -1, sd = 2) mvn(modelName = "X", x)

problem with convergence in mle2/optim function
Hello R Help, I am trying solve an MLE convergence problem: I would like to estimate four parameters, p1, p2, mu1, mu2, which relate to the probabilities, P1, P2, P3, of a multinomial (trinomial) distribution. I am using the mle2() function and feeding it a time series dataset composed of four columns: time point, number of successes in category 1, number of successes in category 2, and

non-standard boot floppys
I experimented with floppy sizes. Eg. I used FDFORMAT v1.8 to format a Disk fdformat a: t82 s21 D10 (I even have a modified version of FDFORMAT that creates only 1 FAT to save space, but I'm not using that.) All the information is written nicely to the Boot-Record http://home.freeuk.com/foxy2k/disk/disk3.htm But SYSLINUX seems to ignore the information. While DOS boots fine from these

VoiceMail without password? How?
If my extension is 22, and voice mail access number is 909, then with exten => 909,1,voicemailmain(s22) I can access voice mail 22, without number and password prompt. But, I want that every extension can access its voice mail without number and password. So, when I put exent => 909,1,voicemailmain(${calleridnum}) voicemail want only password.
