autologistic modelling in R
Hi, I have spatially autocorrelated data (with a binary response variable and continuous predictor variables). I believe I need to do an autologistic model, does anyone know a method for doing this in R? Many thanks C Bell

autologistic model? - what package?
Dear all, Could you pleas advise me on the following? I need to use general(ized) linear models (binomial distribution + logit link function) , to describe the preferred environment of each species (each sample is an individual in which I have measured several variables and also recorded the species it belongs to) However, must account for the spatial autrefoocorrelation between

autologistic regression with Gibbs sampler
Hello everyone, I have some binary, spatially autocorrelated data I would like to run autologistic regression on. I hope to incorporate both ordinary covariates (environmental predictors) and a spatial autocovariate in the model, ideally with a second-order neighbourhood structure. Since my computing skills are limited, I am wondering if anyone has composed an algorithm for this purpose, and

Error in spdep: system is computationally singular
Hi all, I am trying to run an autologistic model using the function errorsarlm from spdep package. **I built an XY matrix extracting the two colums from matriz** coords1<-matriz[matriz$casos1==1, c(4,5)] coords1<-as.matrix(coords1) **I identify neighbours of region points** nb20<-dnearneigh(coords1,0,20,longlat=TRUE) ** I build a neighbours list with spatial weights**

LSD-test
The model should be class aov or lm and my model class is aovlist. tried tidy from broom library but did not work. To make it class aov, I had to remove the error term; model <- aov(Rotationdata_R$`GY(Mg/ha)`~Rep+code*as.factor(Nitrogen),data=Rotationdata_R) Ahmed Attia, Ph.D. Agronomist & Soil Scientist On Mon, Dec 25, 2017 at 7:38 PM, David Winsemius <dwinsemius at

Rtools is not available for the current version of R. What I'm looking for is an alternative package or how others have managed to create workarounds.

ISO3 code to 7 continents names
df is a data frame consisting of one variable (iso3 codes) such as USA RUS ARG BGD ITA FRA Some of these iso3 codes are repeated and I would like the corresponding continent name, the countrycode package does not seem to distinguish between North and South America.

"prob" package alternative
Yes, that is exactly what I was doing two days ago. Warning in install.packages : installation of package ?fAsianOptions_3010.79.tar.gz? had non-zero exit status Which is what a reading of the explanation for why "prob" was retired leads one to expect. Do you have some other suggestion about how to get it to work? I notice you're not using Windows which might have a relationship

"prob" package alternative
Yes. That's the version I've been discussing that has non-zero exit status. That situation is why CRAN retired the prob package. It's possible you installed that library earlier in development and it's been "carried" along. It no longer installs, now. The problems with all of this seem to have started this month according to the conversations. However, no one has
