Read-Write Support for 'NumPy' Files via 'Rcpp'

v0.2.15 · Mar 13, 2026 · GPL (>= 2)

Description

The 'cnpy' library written by Carl Rogers provides read and write facilities for files created with (or for) the 'NumPy' extension for 'Python'. Vectors and matrices of numeric types can be read or written to and from files as well as compressed files. Support for integer files is available if the package has been built with as C++11 which should be the default on all platforms since the release of R 3.3.0.
