Readme for dataframe-0.2.0.0
[back to package description]DataFrame
An intuitive, dynamically-typed DataFrame library.
A tool for exploratory data analysis.
Installing
CLI
- Install Haskell (ghc + cabal) via ghcup selecting all the default options.
- To install dataframe run
cabal update && cabal install dataframe - Open a Haskell repl with dataframe loaded by running
cabal repl --build-depends dataframe. - Follow along any one of the tutorials below.
Jupyter notebook
- Use the Dockerfile in the ihaskell-dataframe to build and run an image with dataframe integration.
- For a preview check out the California Housing notebook.
What is exploratory data analysis?
We provide a primer here and show how to do some common analyses.
Coming from other dataframe libraries

Example usage
Code example
import qualified DataFrame as D import DataFrame ((|>)) main :: IO () df <- D.readTsv "./data/chipotle.tsv" print $ df |> D.select ["item_name", "quantity"] |> D.groupBy ["item_name"] |> D.aggregate (zip (repeat "quantity") [D.Maximum, D.Mean, D.Sum]) |> D.sortBy D.Descending ["Sum_quantity"] Output:
---------------------------------------------------------------------------------------------------- index | item_name | Sum_quantity | Mean_quantity | Maximum_quantity ------|---------------------------------------|--------------|--------------------|----------------- Int | Text | Int | Double | Int ------|---------------------------------------|--------------|--------------------|----------------- 0 | Chips and Fresh Tomato Salsa | 130 | 1.1818181818181819 | 15 1 | Izze | 22 | 1.1 | 3 2 | Nantucket Nectar | 31 | 1.1481481481481481 | 3 3 | Chips and Tomatillo-Green Chili Salsa | 35 | 1.1290322580645162 | 3 4 | Chicken Bowl | 761 | 1.0482093663911847 | 3 5 | Side of Chips | 110 | 1.0891089108910892 | 8 6 | Steak Burrito | 386 | 1.048913043478261 | 3 7 | Steak Soft Tacos | 56 | 1.018181818181818 | 2 8 | Chips and Guacamole | 506 | 1.0563674321503131 | 4 9 | Chicken Crispy Tacos | 50 | 1.0638297872340425 | 2 Full example in ./app folder using many of the constructs in the API.
Visual example
Future work
- Apache arrow and Parquet compatability
- Integration with common data formats (currently only supports CSV)
- Support windowed plotting (currently only supports ASCII plots)
- Create a lazy API that builds an execution graph instead of running eagerly (will be used to compute on files larger than RAM)
