Hello Is there any function to calculate White's standard errors in R in an NLS regression. The sandwich and car package do it but they need an lm object to calculate the error's. Does anyone have idea how to do it for an NLS object ?

Hi, I am having some trouble trying to install a number of packages in R on my work computer.

Hi all, Xiph aims at developing open-standards media formats. Though xiph.org tells about vorbis/theora/flac/speex, nothing is mentioned about container to use (that is ogg/ogm). I have a few questions Is there a difference between ogg and ogm? I guess its only the extension that is different and everything else is same. Some tools (like ogmtools) are available to create ogm files. What is

Hi, I am writing a function to dynamically create column names and fill those columns with some basic calculations. My function "demo_fn" takes argument "blup_datacut" and I like to use the contents of those arguments to dynamically create new columns in my dataset. Please note that I have another function called "calc_gg" within the function "demo_fn".

Hi, I don't know about the lazyeval package or what you are trying to do but to answer the main question "How to create columns dynamically using a function?" I would do something like that: # dataset dem <- structure(list(id = c("L1", "L2", "L3", "M1", "M2", "M3"), TEST_SET_NAME = c("A", "A",

Your code contains the lines stopifnot(!(any(data1$norm_sd >= 1))) if (!(any(data1$norm_sd >= 1))) { df1 <- dat1 return(df1) } stop() "throws an error", causing the current function and all functions in the call stack to abort and return nothing. It does not mean to stop now and return a result. Does the function give

Hi, I have configured a certified asterisk 13 server with chan_mobile and res_pjsip. I have a Cisco 7940 hardphone and I use ekiga as softphone client. Now the problem is, using the hardphone I'm able to call the softphone and hear everything properly. But when I call from the hardphone to some number that has to be dialed via chan_mobile, I'm not able to hear what the other side says (I

If you are trying to understand why the "stopifnot" condition is met you can replace it by something like: if ( any(dat2$norm_sd >= 1) ) browser() This will put you in a debugging session where you can examine your variables, e.g. > dat$norm_sd HTH, Eric On Thu, Dec 14, 2017 at 5:33 PM, Eric Berger <ericjberger at gmail.com> wrote: > The message is coming from

Eric: I will try and see if I can figure out the issue by debugging as you suggested. I don?t know why my code after stopifnot is not getting executed where I like the code to run the funlp2 function when the if statement is TRUE but when it is false, I like it to keep running until the stopifnot condition is met. When the stopifnot condition is met, I like to get the output from if statement

Hi David/Renato, By AST I mean Abstract Syntax Tree. We are writing an optimization pass for some FORTRAN95 + MPI code that requires us to analyze the AST. We thought of 2 ways of doing this: 1. Compile the code using Clang/llvm-gfortran, get the textual AST dump (somehow), analyze the AST dump using Ruby, modify it and then feed back the modified AST to LLVM. 2. Do the analysis as an LLVM

Probably for high-level optimisations, or just to see if the parser is good, as I do in my compiler. But AST is

(Theora/Vorbis) available. Message-ID: <410011E4.2040904@hut.fi> Hello, I noticed that it's quite difficult currently to create Ogg format files (Ogg Theora for video and Ogg Vorbis for audio). There's only the encoder_example-program, which is included in the libtheora source packages, but seemingly not in any libtheora/libtheora-devel packages that are around the web for e.g.

Hi, I want to fit the following model to my data: Y_t= a+bY_(t-1)+cY_(t-2) + Z_t +Z_(t-1) + Z_(t-2) + X_t + M_t i.e. it is an ARMA(2,2) with some additional regressors X and M. [Z_t's are the white noise variables] How do I find the estimates of the coefficients in R? And also I would like to know what technique R employs to find the estimates? Any help is appreciated. Thanks,

Hello, I've been trying to answer a problem I have had for some months now and came across multivariate multilevel modeling. I know MPLUS and SPSS quite well but these programs could not solve this specific difficulty. My problem: 9 correlated dependent variables (medical symptoms; categorical, 0-3), 5 measurement points, 10 time-varying covariates (life events; dichotomous, 0-1), N ~ 900.
