add_meta: Add metadata to the disk.frame

Description

This is the only mechanism to add metadata to a disk.frame at the moment.

Usage

add_meta(df, ..., nchunks = nchunks.disk.frame(df), shardkey = "",
  shardchunks = -1)

Arguments

df

a disk.frame

...

any other metadata the user wishes to keep.

nchunks

# adding some useless metadata to the repo
add_meta(cars.df, useless = TRUE)

# clean up
delete(cars.df)
