I am not an expert wrt gota/dataframe but here is what I got:
$> go run ./main.go
$> cat out.csv
COL.1,COL.2,COL.3
b,1,3.000000
a,2,4.000000
with the following main.go file:
package main
import (
"log"
"os"
"github.com/kniren/gota/dataframe"
"github.com/kniren/gota/series"
)
func main() {
df := dataframe.New(
series.New([]string{"b", "a"}, series.String, "COL.1"),
series.New([]int{1, 2}, series.Int, "COL.2"),
series.New([]float64{3.0, 4.0}, series.Float, "COL.3"),
)
o, err := os.Create("out.csv")
if err != nil {
log.Fatal(err)
}
defer o.Close()
err = df.WriteCSV(o)
if err != nil {
log.Fatal(err)
}
err = o.Close()
if err != nil {
log.Fatal(err)
}
}
