ramify (version 0.1.0)

ramify: ramify: additional matrix functionality

Description

Additional matrix functionality for R. Includes a new wrapper for the built-in matrix function that extends its functionality by allowing matrices to be created from character strings and lists. A number of convenience functions have also been added for users more familiar with MATLAB or Julia.

Details

The main functions in this package are:

• mat- matrix wrapper function
• bmat- like the character method ofmat, but for block matrices
• dmat- likemat, but instead returns a data frame
• eye- creates an identity matrix
• hcat/vcat- concatenate matrices
• fill- fills a matrix with a particular value
• flatten- flatten (i.e., collapse) a matrix to one dimension
• inv- calculates the inverse of a square matrix
• linspace/logspace- constructs a vector of linearly-spaced/logarithmically-spaced elements
• ones/zeros- creates a matrix of all ones/zeros
• rand/randn- creates a matrix of uniform/normally distributed random numbers
• resize- resize a given matrix
• size- returns the dimensions of the matrix
• trues/falses- creates a matrix of allTRUEs/FALSEs
