The Dinah package provides data structures and fetch functionality for MLB's Statcast and Chadwick's Register datasets.
go get -u github.com/fischersean/dinah
Consider we wanted to download pitch by pitch Statcast data for the month of September 2020.
package main
import (
"fmt"
"time"
"github.com/fischersean/dinah/statcast"
)
func main(){
d0 := time.Date(2020, time.September, 1, 0, 0, 0, 0, time.UTC)
d1 := time.Date(2020, time.September, 30, 0, 0, 0, 0, time.UTC)
ds, err := statcast.FromHttp(d0, d1)
if err != nil {
panic(err)
}
fmt.Println("%#v\n", ds)
}If we wanted to patch up the MLBAM id's for the players within the Statcast data, we could pull the mapping from Chadwick's people register. It's recommended to use a local file for this. The full dataset is 45+MB and may dramatically slow execution time.
package main
import (
"fmt"
"time"
"github.com/fischersean/dinah/chadwick"
)
func main(){
people, err := chadwick.PeopleFromCsv("cwickpeople.csv")
if err != nil {
panic(err)
}
fmt.Println("%#v\n", people)
}
