Perform the computation; same as calling cmap without .f and lazy = FALSE
# S3 method for disk.frame
compute(x, name = NULL, outdir = tempfile("tmp_df_", fileext = ".df"), ...)
Arguments
- x
a disk.frame
- name
If not NULL then used as outdir prefix.
- outdir
the output directory
- ...
Passed to `write_disk.frame`
Examples
cars.df = as.disk.frame(cars)
cars.df2 = cars.df %>% cmap(~.x)
# the computation is performed and the data is now stored elsewhere
cars.df3 = compute(cars.df2)
# clean up
delete(cars.df)
delete(cars.df3)
