Privacy Preserving Record Linkage (PPRL)
A toolbox for deterministic, probabilistic and privacy-preserving record linkage techniques. Combines the functionality of the ‘Merge ToolBox’ (<> ) with current privacy-preserving techniques.

Convert Base Plot to ‘grob’ Object (base2grob)
Convert base plot function call (using expression or formula) to ‘grob’ object that compatible to the ‘grid’ ecosystem. With this package, we are able to e.g. using ‘cowplot’ to align base plots with ‘ggplot’ objects and using ‘ggsave’ to export base plot to file.

Spatial ARCH and GARCH Models (spGARCH) (spGARCH)
A collection of functions to deal with spatial and spatiotemporal autoregressive conditional heteroscedasticity (spatial ARCH and GARCH models) by Otto, Schmid, Garthoff (2017) <arXiv:1609.00711>: simulation of spatial ARCH-type processes (spARCH, exponential spARCH, complex spARCH); quasi-maximum-likelihood estimation of the parameters of spARCH models and spatial autoregressive models with spARCH disturbances, diagnostic checks, visualizations.
