Convert files to and from IDX format to vectors, matrices and arrays. IDX is a very simple file format designed for storing vectors and multidimensional matrices in binary format. The format is described on the website from Yann LeCun < http://yann.lecun.com/exdb/mnist/>.
This package provides functions to convert files to and from IDX format to arrays in R. IDX is a format to store vector and arrays in binary format.
Reading IDX format is needed for instance to use the MNIST database of handwritten digits provided by Yann LeCun.
This basic example downloads, uncompresses and reads the IDX file from the train set of the MNIST data.

The package can be installed from GitHub with the following command:
$ R -e "devtools::install_github('edoffagne/idx2r')"
