Abstract:
|
Aleph is an open-source project to create the next generation of statistical computing software, possibly as a successor to R. The goal is to provide a modern, flexible system suitable for statistical analysis. All aspects of the project are currently experimental and up for discussion. The current experimental implementation is written in C and features its own C-level object system.
Although other approaches were considered, so far we have decided to use the core S/R language as the basis for the Aleph language. The syntax should be very similar such that it should be possible to translate packages from R to Aleph if necessary (not really a requirement but a side-effect). However, some aspects of the language (lazy evaluation, pass-by-value, etc.) are not mandatory. One of the key points is that Aleph has its own object system. Some major features are first-class class objects, fundamentally complete class structure, type matched function arguments.
