MRG: Create Non-Confidential Multi-Resolution Grids

The need for anonymization of individual survey responses often leads to many suppressed grid cells in a regular grid. Here we provide functionality for creating multi-resolution gridded data, respecting the confidentiality rules, such as a minimum number of units and dominance by one or more units for each grid cell. The functions also include the possibility for contextual suppression of data. For more details see Skoien et al. (2025) <doi:10.48550/arXiv.2410.17601>.

Function to create a gridded (usually multi-resolution grid) from a data.frame or csv file with information about the corners and resolution, as typically can be downloaded from Eurostat. The function can also save the grid as a geo-object.	MRGfromDF
Merge two or more multi-resolution grids to a common resolution	MRGmerge
Function that finds and merges overlapping grid cells in a multi-resolution grid The need for this function comes from an error in the gridding process, and it can be seen as symptom solving rather than solving the issue. This function will either just show the problematic grid cells or remove the overlaps.	MRGoverlap
Convenience function based on ggplot2 to plot multi-resolution grids with some default suggestions For full flexibility it is better to use ggplot2 directly.The function can also be used for ordinary grids	MRGplot
