Functions to write a vector x into a series of binary files.

1 2	writeBinBlocks(x, pattern, maxRows=10000, path=".", what = c("double", "integer", "character"), append = FALSE, verbose = TRUE)

`x`	A `character` string to specify the name of the binary file.
`path`	A `character` string to specify the path to input binary file.
`what`	A `character` string denoting the mode of the data to be read, one of: '"double", "integer", "character"'.
`append`	A `logical` value. If `FALSE`, then existing files will be overwritten. Otherwise, data will be appended onto the existing file.
`pattern`	A `character` string to specify the common prefix for a series of binary files.
`maxRows`	An `integer` to specify the maximum number of rows allowed in a single binary file. See details for more information.
`verbose`	A `logical` value specifying whether or not to print verbose messages.

To facilitate handling large data, function writeBinBlocks is provided, in which a long x is split into several small parts, each containing less than maxRows rows. A series of binary files, like [pattern]1, [pattern]2, [pattern]3, ..., will be thus generated.

returns an invisible NULL.
