as.data.frame.disk.frame: Convert disk.frame to data.frame by collecting all chunks

In disk.frame: Larger-than-RAM Disk-Based Data Manipulation Framework

Convert disk.frame to data.frame by collecting all chunks

Description

Convert disk.frame to data.frame by collecting all chunks

Usage

## S3 method for class 'disk.frame'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)

Arguments

x	a disk.frame
row.names	NULL or a character vector giving the row names for the data frame. Missing values are not allowed.
optional	logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.
...	additional arguments to be passed to or from methods.

Examples

cars.df = as.disk.frame(cars)
as.data.frame(cars.df)

# clean up
delete(cars.df)
