Create a disk.frame from a folder
disk.frame(path, backend = "fst")The path to store the output file or to a directory
The only available backend is fst at the moment
path = file.path(tempdir(),"cars")
as.disk.frame(cars, outdir=path, overwrite = TRUE, nchunks = 2)
#> path: "C:\Users\RTX2080\AppData\Local\Temp\RtmpCo1OFr/cars"
#> nchunks: 2
#> nrow (at source): 50
#> ncol (at source): 2
df = disk.frame(path)
head(df)
#> speed dist
