Re: [R] [DKIM] Batch Installer for R [SEC=UNCLASSIFIED]

Hi Tobias, Here is something I acquired from this mailing list some years ago. It works well for me: #---run in previous version (e.g. R 3.1.0) packages <- installed.packages()[,"Package"] save(packages, file="Rpackages_R3.1.0") #---run in new version load("Rpackages_R3.1.0") for (p in setdiff(

code? example data? We can only guess based on your vague post. "PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code." Moreover, this sounds like a statistical question, not a question about R programming,

[R] reduced set of alternatives in package mlogit

I'm trying to estimate a multinomial logit model but in some choices only alternatives from a subset of all possible alternatives can be chosen. At the moment I get around it by creating "dummy" variables to mean the alternative is not available and let it estimate this coefficient as highly ne

[R] Installing specific version of R

Hi, When I am trying to install specific version of R , using apt-get -y --force-yes install r-base=3.2.1-4precise0 r-recommended=3.2.1-4precise0 r-base-dev=3.2.1-4precise0, I do see correct version being set up in in the logs , but the installed version shows me 3.2.4. Is there anything

In the rockchalk package, I want to provide functions for regression objects that are "well behaved." If an object responds to the methods that lm or glm objects can handle, like coef(), nobs(), and summary(), I want to be able to handle the same thing. It is more difficult than expected to ask a

[R] Batch Installer for R

Hi everyone, in Python, you can run pip install -r filename to install all packages listed in the file. Is there something similar to R? If not, isn't it quite easy to write? For me, it would be much easier to work on projects with other people if I could just install all dependencies with one li

Re: [R] Convergence issues when using ns splines (pkg: spline) in Cox model (coxph) even when changing coxph.control

Thanks to David for pointing this out. The "time dependent covariates" vignette in the survival package has a section on time dependent coefficients that talks directly about this issue. In short, the following model is simply wrong: coxph(Surv(time, status) ~ trt + prior + karno + I(karn

[R] function to carry out Bootstrap LRT with poLCA results

Dear List, I would like to determine the optimal number of latent classes (polytomous data) using Bootstrap LRT. poLCA does not provide such a possibility and I am not enough into programming to modify the code. Is there any other way to do this, e.g. use a poLCA object with some other package?
