as.data.frame.disk.frame: 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 disk.frame
as.data.frame(x, row.names, optional, ...)

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

# NOT RUN {
cars.df = as.disk.frame(cars)
as.data.frame(cars.df)

# clean up
delete(cars.df)
# }
