Readme for dataframe-0.1.0.1
[back to package description]DataFrame
An intuitive, dynamically-typed DataFrame library.
A tool for exploratory data analysis.
Installing
- 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.
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 Data.DataFrame as D
import Data.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

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)
