big.data.frame: Create a big.data.frame

In jayemerson/big.data.frame: Extend big.char and bigmemory's big.matrix to support larger-than-RAM data.frame-like objects in R.

Description

Create a big.data.frame

Usage

big.data.frame(nrow, classes, location = NULL, names = NULL,
  maxchar = NULL, init = NULL)

Arguments

nrow	the number of rows
classes	a vector of values from 'double', 'character', ...
location	folder to contain the object backingfiles, or NULL if the object will be in-RAM.
names	a vector of names for the columns (variables)
maxchar	a vector with NA for numeric columns, but integers specifying the maximum number of characters for string columns (see big.char for more information).
init	a vector of values for initialization; note that for large objects this will slow down the creation substantially.
