My developments are located on my [GitHub](https://github.com/tobiste/) page. 
They are free and open-source and I try to keep them up to date. 
Feel free to contribute, comment or open an issue!

## R packages

### tectonicr {#sec-tectonicr}

::: {.grid}

::: {.g-col-9}
tectonicr is a free and open-source R package for modeling and **analyzing the direction of the maximum horizontal stress** (SHmax) based on the empirical link between the orientation of intraplate stress and 
the direction of the relative motion of neighboring plates [see @Stephan2023]. 
You can download and install it directly from the CRAN server using `install.packages("tectonicr")` in R. 
A beta version is on [github](https://github.com/tobiste/tectonicr/).

### geoprofiler

geoprofiler is a free, open-source R package that allows you to create SWATH profiles and 
"data transects", which are geological parameters plotted against the distance along a 
user-defined profile line.
This is useful whenever you want to analyze the trend of values (e.g., geochemical compositions, ages, depth, and magnitudes) with the distance to an important structure. 
You can download and install it directly from the CRAN server using `install.packages("geoprofiler")` in R. 
A beta version is available through [github](https://github.com/tobiste/geoprofiler/).

### structr (beta)

::: {.grid}

::: {.g-col-9}

Structural geology package for R, free and open-source. It provides functions to

-   analyze and visualize orientation data such as faults, folds, bedding planes, and lineations.
-   analyze and visualize the magnitudes of stress in the Mohr Circle.
-   reconstruct the orientation of structures in oriented drill cores using the alpha, beta, and gamma angles
-   paleostress analysis using slip inversion
-   vorticity and strain analysis
-   simulation of deformation using deformation and velocity gradient tensors
-   easy import: import your structural data directly from StraboSpot projects
