[R] Change of language interface in R

Can anyone please tell me how to change the language interface so as to receive error messages in English. Currently it's a mixed jargon of French an English. Thank you for any help. Anne [[alternative HTML version deleted]] __ R-help@r-proj

Re: [R] Code modification for post-hoc power

d it a range of powers and find the one for which it calculates the sample size you had. There is a more elegant way to do this using uniroot but brute force should work. Michael On 26/08/2019 13:42, Marc Schwartz via R-help wrote: > >> On Aug 26, 2019, at 6:24 AM, CHATTON An

[R] Code modification for post-hoc power

Hello everybody, I am trying to accommodate the R codes provided by Donohue for sample size calculation in the package "longpower" with lmmpower function to estimate the post-hoc power (asked by a reviewer) of a binary GEE model with a three-way interaction (time x condition x continuous predic

Re: [R] Strange paradox

Dear all, Thank you for your remarks. The data under analysis were multiply-imputed using Mice. To compare the nested models, I used the following R codes by van Buuren: pool.compare (Model2, Model1, method = c("wald"), data = NULL) As far as I know the Wald statistic tests the null hypothesis that

[R] Strange paradox

Hello, I am currently analysed two nested models using the same sample. Both the simpler model (Model 1 ~ x1 + x2) and the more complex model (Model 2 ~ x1 + x2 + x3 + x4) yield the same adjusted R-square. Yet the p-value associated with the deviance statistic is highly significant (p=0.0047),

[R] Problems to obtain standardized betas in multiply-imputed data

Dear all, I am having problems in obtaining standardized betas on a multiply-imputed data set. Here are the codes I used : imp = mice(data, 5, maxit=10, seed=42, print=FALSE) FitImp <- with(imp,lm(y ~ x1 + x2 + x3)) Up to here everything is fine. But when I ask for the standardized coefficients

[R] Further questions

Hi R folks, In my previous post I forgot to mention that I was new to R. I was really grateful for your quick help. I have two further questions: 1) In the graph of a regression line I would like to show one specific residual yi obs - yi pred (let's take the person whose residual is 76). How do I
