@juliasilge Thanks! When I start positron from the command line in some directory, the directory shown is always ~ (i.e., my home directory); this is on linux. How do you start positron, or how could I do this differently? Maybe clicking some kind of project file?

gpboost: Combining Tree-Boosting with Gaussian Process and Mixed Effects Models
An R package that allows for combining tree-boosting with Gaussian process and mixed effects models. It also allows for independently doing tree-boosting as well as inference and prediction for Gaussian process and mixed effects models. See <https://github.com/fabsig/GPBoost> for more information on the software and Sigrist (2022, JMLR) <https://www.jmlr.org/papers/v23/20-322.html> and Sigrist (2023, TPAMI) <doi:10.1109/TPAMI.2022.3168152> for more information on the methodology.

```
library(sf)

data <- st_read('~/Downloads/bizkaia_elementos_test.gpkg') |> st_make_valid()

i <- st_intersection(data)
i2 <- […]
