Crate pspp 

PSPP in Rust

PSPP is a program for statistical analysis of sampled data. It is a free replacement for the proprietary program SPSS.

This is an experimental rewrite of PSPP in Rust. It includes both programs directly useful to users and a library that can be used by other software. The goal of the rewrite is to ensure that PSPP can be as robust as possible, while remaining fast and portable.

This new version is very incomplete–in fact, only a subset of the pspp-convert utility is really ready for use.

Installing PSPP

To install PSPP in Rust from source, install Rust, version 1.88 or later. Then, either:

• Use the following command to download PSPP source code from crates.io and build and install it:

  cargo install pspp

• Clone a local copy of this repository and build and install it from there, with: can instead cd into rust/pspp in the source tree and run:

  git clone git://git.sv.gnu.org/pspp
  cd pspp/rust/pspp
  cargo install --path .

The above commands also work for upgrades.

Uninstalling

To uninstall PSPP, run:

cargo uninstall pspp

Running PSPP

After installing PSPP using one of the methods above, run it with:

pspp

For help, use pspp --help. The only really useful PSPP commands currently are convert and show. Help for individual commands is available with pspp <command> --help.

Reading the manual

The PSPP manual may be read online.

To build the manual, install mdBook using its instructions then, from the root of a checked-out copy of this repository, build the manual with:

(cd rust/doc && mdbook build)

This will output the manual as HTML under rust/doc/book/html.

Reporting bugs

As this is an experiment, please don’t have high expectations (yet). However, questions and comments about using PSPP may be sent to pspp-users@gnu.org. Please email bug reports to bug-gnu-pspp@gnu.org or file them online at Savannah. Please indicate that you are referring to the Rust rewrite.
