# tech.ml.dataset
`tech.ml.dataset` (TMD) is a Clojure library for tabular data processing similar to Python's Pandas, or R's `data.table`. It supports pragmatic data-intensive work on the JVM by providing powerful abstractions that simplify implementing efficient solutions to real problems. Datasets [shrink in memory](https://gist.github.com/cnuernber/26b88ed259dd1d0dc6ac2aa138eecf37) through columnar storage and the use of primitive arrays, packed datetime types, and string tables.
Unlike in Python or R, TMD datasets are _functional_, which means they're easier to reason about.
## Installing
Installation instructions for your favorite build system (lein, deps.edn, etc...) can be found at Clojars, where the library is hosted:
[](https://clojars.org/techascent/tech.ml.dataset)

## Verifying Installation
```clojure
user> (require 'tech.v3.dataset)
nil
user> (->> (System/getProperties)
(map (fn [[k v]] {:k k :v (apply str (take 40 (str v)))}))
(tech.v3.dataset/->>dataset {:dataset-name "My Truncated System Properties"}))
