similar to: where is internal function of sample()?

Hello list, I am dealing with a noisy function (gradient,hessian not available) with simple boundary constraints (x_i>0). I've tried constrOptim() using nelder mead to minimize it but it is way too slow and the returned results are not satisfying. simulated annealing is so hard to tune and it always crashes R program in my case. I wonder if there are any packages or functions can do

Hi list, I am building a regression model with categorical predictor variable coded by treatment contrasts. The summary of the regression model shows that some levels are significant while others are not. The significant ones show that they are statistically significant from the basis factor (at level 0). How do we generally deal with those insignificant levels? If they are used for

Hi list, I tried to use nls to do some nonlinear least square fitting on my data with 340 observations and 10 variables, but as I called nls() function, I got this error message: Error in qr.qty(QR, resid) : 'qr' and 'y' must have the same number of rows Then I traced back a little bit into nls() function, the error seemed to happen when calling nlsiter() internal function, but

I am trying to get documentation about the random number generator used in "sample". The help for sample does not mention it. Can anyone point me in the right direction. Thanks [[alternative HTML version deleted]]

FWIW, I suspect this is related to the function R_unif_index that was introduced in src/main/RNG.c around revision 72356, or the way this function is used in do_sample in src/main/random.c. 20.9.18 08:19, Wolfgang Huber scripsit: > Besides wording of the documentation re truncating vs rounding, there is > something peculiar going on with the fractional part of n: > > >

Hi all, I would like to determine if an ALTREP object is from my package, I see there is a function `ALTREP_CLASS` defined in RInternal.h but its return value is neither a `R_altrep_class_t` object nor an STRSXP representing a class name. I do not know how to correctly use it. Any suggestions? Thanks, Jiefei [[alternative HTML version deleted]]

Benjamin, You happened to send a link which points to the OP's own package :) I think Jiefei would like to know how one can "officially" determine if an arbitrary ALTERP object belongs to a class that he owns.

Hi All I have been struggling with this model for some time now and I just can't get it to work correctly. The messages I get when running the code is: DLSODA- Warning..Internal T (=R1) and H (=R2) are such that in the machine, T + H = T on the next step (H = step size). Solver will continue anyway. In above message, R = [1] 0 0 DINTDY- T (=R1) illegal In above message, R = [1]

Hi all, I'm wondering if there is any way to define a `SET_ELT` function for an ALTREP class? I see there are ` ALTINTEGER_SET_ELT` etc. functions exported in Rinternal.h, but there is no corresponding ALTREP APIs to define them. The only way to set the value of an ALTREP is through a pointer, which will require that the ALTREP data is in memory. Is it on purpose? Will there be any plan to

A colleague sent me the following: If you specify probabilities in the 'sample' function and forget to type 'prob=...', then you get nonsense. E.g. sample(1:10,1,c(0,0,0,0,1,0,0,0,0,0)) does not filter '5', while sample(1:10,1,prob=c(0,0,0,0,1,0,0,0,0,0)) does it correctly. I wish this would return an error because the

Dear all, I am grateful if anyone provides a solution to my problem of no y-axis label using png on linux. If I use postscript device or X11 device, it is fine. On Windows, it works with png. I have tried different versions of R and none of them works.

I don?t know if the last message was with content. So, I sent again. I have installed a Digium card TE210P and unicall for use MFC/R2. I think that it?s all right but I can?t make and receive calls.

Hi, on ia64, the do_* functions for hypercalls are called in C. However, they are not declared in any .h file. I think it is cleaner to declare them in an header file rather than locally. The question is in which header file. Thank you for any suggestion. The do_* functions are at least: extern long do_ni_hypercall(void); extern long do_dom0_op(dom0_op_t *u_dom0_op); extern long
