similar to: R Source Code

Currently demo calls source with a hard coded max.deparse.length = 250 so you can't really see the demo properly in some cases. Note the [TRUNCATED] below. (1) It would be nice if demo passed max.deparse.length (and other args to source). (2) Also a larger max.deparse.length default would be nice to make it less likely one would have to set it in the first place. > R.version.string #

Dear R Core, working on my dynamic factor modelling package, which requires several subroutines to create and update several system matrices, I come back to the issue of being annoyed by R not supporting multiple assignment out of the box like Matlab, Python and julia. e.g. something like A, C, Q, R = init_matrices(X, Y, Z) would be a great addition to the language. I know there are several

Dear all, A question related to the following has been asked on R-help before, but I could not find any answer to it. Input will be much appreciated. I got an unexpected sign of the "slope" parameter associated with a covariate (diam) using zeroinfl(). It led me to compare the estimates given by zeroinfl() and hurdle(): The (significant) negative estimate here is surprising, given

An attachment called (WORM_SOBIG.C) in an email that appears to have been sent from your email address to (arrowcomp at xtra.co.nz) contained the virus (WORM_SOBIG.C), which has been deleted. If you do not believe you were the actual sender, the Klez virus is likely to be the culprit. The Klez virus works by forging the 'From' address inside the virus infected email, which means you can

Hello, I'm using pscl to run a hurdle model. Everything works great until I get to the point of making predictions. All of my "count" predictions are lower than my actual data, and lower than the "response" predictions, similar to the issue described here ( https://stat.ethz.ch/pipermail/r-help/2012-August/320426.html) and here (

Dear Listers, I have a general statistical question. Are hurdle logit-poisson model and posson model nested? Thank you so much?

Dear list, I am using the hurdle model for modelling the habitat of rare fish species. However I do get an error message when I try to model my data: > test_new1<-hurdle(GALUMEL~ depth + sal + slope + vrm + lat:long + offset(log(haul_numb)), dist = "negbin", data = datafit_elasmo) Error in hurdle(GALUMEL ~ depth + sal + slope + vrm + lat:long + offset(log(haul_numb)), :

I am interested in utilizing this so called "double hurdle" model in my study. We can write the model in the following way: if (z'a + u > 0 & x'b + e > 0) y = x'b + e, else y = 0 In the model, consumption y is the (left-) censored dependent variable. e and u are the normally distributed error terms. z'a is the participation equation and x'b is the

Hi, I have to R fairly recently from Matlab, where I have been used to organising my own custom functions into directories which are adding to the Matlab search path. This enables me to call them as I would one of Matlab's built-in functions. I have not found a way of doing the same thing in R. I have resorted to using source() on symlinks located in the current directory. Not very

Hello, I have been using mgcv to run GAM hurdle models, analyzing presence/absence data with GAM logistic regressions, and then analyzing the data conditional on presence (e.g. without samples with no zeros) with GAMs with a negative binomial distribution. It occurs to me that using the negative binomial distribution on data with no zeros is not right, as the negative binomial allows zeros.

Hi Guys, i've successfully installed the current bristuff, everything works fine, exept one thing: As soon as i pick up the phone that is connected to the bri-card, asterisk jumps into extension s of the context that is specified in zapata.conf, if i have immediate=no then i hear the normal dialtone for about 1/10 of a second. Any hints what i'm doing wrong? If i dial the number

I'm trying to move from Matlab to R, and I'm stuck even getting started. This sounds to me like the dumbest question in the world but... how does one put R source code in files? Over the last three days I've gone front to back through the Introduction to R and the R Language Definition, and while I'm excited that the language is so Lispish, none of what I read described how to

This request is related to the following post from last year: https://stat.ethz.ch/pipermail/r-help/2011-June/279752.html After reading the thread, the idea is still not clear. I have fitted a model using HURDLE from the PSCL package. I am trying to get marginal effects / slopes by multiplying the coefficients by the mean of the marginal effects (I think this is right). To my understanding, this

Hi all-- We are planning an intervention study for adolescent alcohol use, and I am planning to use simulations based on a hurdle model (using the hurdle() function in package pscl) for sample size estimation. The simulation code and power code are below -- note that at the moment the "power" code is just returning the coefficients, as something isn't working quite right. The

Ok, now thats a gadget i want to have :-) http://www.global-teck.com/english/newproduct.php http://www.global-teck.com/english/telecomproducts.php Anyone knows something similar that would work with asterisk, or any chances getting this to work?

I've ported somebody else's rather cumbersome Matlab model to R for colleagues that want a free build of the model with the same type of I/O. The Matlab model reads a text file with the initial parameters specified as: C:\Data\Carluc\Rport>more Params.R # Number of years to simulate nYears = 50; # Initial year for graphing purposes year0 = 1970; # NPP/GPP ratio (cpp0 unitless) fnr =

Hi all, First post for me here, but I have been reading on the forum for almost two years now. Thanks to everyone who contributed btw! I have a dataset of 4000 observations of count of a mammal and I am trying to predict abundance from a inflated-zero model as there is quite a bit of zeros in the response variable. I have tried multiple options, but I might do something wrong as every

Hello; I am a R newbie and would like to know correct and efficient method for doing string replacement. I have a large data set, where I want to replace character "M", "b", and "K" (currency in Million, Billion and K) to millions. That is 209.7B with (209.7 * 10e6) and 100.00K with (100.00 *1/100) and etc.. d <- c("120.0M", "11.01m",

Dear list, I'm wondering if anyone can help me calculate the deviance of either a zeroinfl or hurdle model from package pscl? Even if someone could point me to the correct formula for calculating the deviance, I could do the rest on my own. I am trying to calculate a pseudo-R-squared measure based on the R^{2}_{DEV} of [1], so I need to be able to calculate the deviance of the full and null
