imager - Image Processing Library Based on 'CImg'

Fast image processing for images in up to 4 dimensions (two spatial dimensions, one time/depth dimension, one colour dimension). Provides most traditional image processing tools (filtering, morphology, transformations, etc.) as well as various functions for easily analysing image data using R. The package wraps 'CImg', <https://cimg.eu>, a simple, modern C++ library for image processing.

ParmOff - Complex Argument Matching

Provides a flexible framework for matching and validating function arguments against user-defined expectations, including named and positional handling, range limits, and logarithmic transforms. It is designed to simplify robust argument processing in reusable code while keeping function interfaces clear, predictable, and easy to extend.

hyper.fit - N-Dimensional Hyperplane Fitting with Errors

High level functions for hyperplane fitting (hyper.fit and visualising (hyper.plot2d / hyper.plot3d. In simple terms this allows the user to produce robust 1D linear fits for 2D x vs y type data, and robust 2D plane fits to 3D x vs y vs z type data. This hyperplane fitting works generically for any N-1 hyperplane model being fit to a N dimension dataset. All fits include intrinsic scatter in the generative model orthogonal to the hyperplane.

snapshot - Gadget N-body cosmological simulation code snapshot format 1 and 2 I/O utilities

Functions for reading and writing Gadget N-body format 1 and 2 snapshots. The Gadget code is popular in astronomy for running N-body / hydrodynamical cosmological and merger simulations. To find out more about Gadget see the main distribution page at www.mpa-garching.mpg.de/gadget/. Format 1 specific functions end with a ".1" suffix and format 2 specific functions end with a ".2" suffix. Generic functions have neither suffix.
