big.factor: Create a big.factor object

In jayemerson/big.char: Provides Very Large Vectors of Character Strings

Description

Create a big.factor object that could be in shared memory or larger-than-RAM via big.char and big.matrix objects.

Usage

big.factor(length, maxchar = 8, init = NULL, levels = NULL,
  backingfile = NULL, backingpath = NULL, descriptorfile = NULL,
  binarydescriptor = FALSE, shared = TRUE)

Arguments

length	the vector length
maxchar	the maximum length of the strings, 8 by default
init	an optional string for initialization purposes
levels	a vector of character factor levels (labels), which may be truncated to maxchar length if necessary.
backingfile	optional name of binary memory-mapped file
backingpath	should be obvious, right?
descriptorfile	the descriptor file associated with the backingfile
binarydescriptor	see big.matrix
shared	see big.matrix

Details

There are real hazards here. I may not finish it now.

Value

a big.factor
