The magic package implements functionality for manipulatinghigh-dimensional arrays using efficient vectorised methods. The originalapplication was high-dimensional magic hypercubes. This README showssome of the more useful functions in the package.

You can install the released version ofmagic fromCRAN with:

# install.packages("magic")  # uncomment this to install the packagelibrary("magic")

• Functionadiag() binds arbitrarily-dimensioned arrayscorner-to-corner
• Functionapad() pads arbitrarily-dimensioned arrays
• Functionapldrop() is a replacement for APL’s drop
• Functionaplus() superimposes two arrays of different dimensionsand returns the sum of overlapping elements
• Functionarev() is a multidimensional generalization ofrev()
• Functionarot() is a generalization of matlab’srotdim
• Functionfnsd() returns the first nonsingleton dimension of anarbitrary dimensioned array
• Functionashift() shifts the origin of arbitrary dimensionedarrays

Much of the package functionality is vectorised in array dimension.
