[R-sig-Geo] landmap package, cannot get the model error following the binomial variable example

[Manuel Spínola]

Dear list members,

I am fitting a model using the package landmap but I cannot get the model
error for the binomial variable example of the package.

data(eberg_grid)
gridded(eberg_grid) <- ~x+y
proj4string(eberg_grid) <- CRS("+init=epsg:31467")

data(eberg)
eb.s <- sample.int(nrow(eberg), 1400)
eberg <- eberg[eb.s,]
coordinates(eberg) <- ~X+Y
proj4string(eberg) <- CRS("+init=epsg:31467")

eberg$Parabraunerde <- ifelse(eberg$TAXGRSC=="Parabraunerde", 1, 0)

X <- eberg_grid[c("PRMGEO6","DEMSRT6","TWISRT6","TIRAST6")]

mB <- train.spLearner(eberg["Parabraunerde"], covariates=X,
   family=binomial(), cov.model = "nugget", parallel=FALSE)

eberg.Parabraunerde <- predict(mB)

eberg.Parabraunerde$pred
