Create Binary Writer Object

Create a new instance of the BinaryWriter class for writing bulk binary data.

Usage

BinaryWriter(
  output,
  byte_offset,
  data_type,
  bytes_per_element,
  endian = .Platform$endian
)

Arguments

output

Character string (file name) or connection object to write to

byte_offset

Integer specifying bytes to skip at start of output

data_type

Character string specifying R data type ('integer', 'double', etc.)

bytes_per_element

Integer specifying bytes per data element (e.g., 4 or 8)

endian

Character string specifying endianness ('big' or 'little', default: platform-specific)

Value

An object of class BinaryWriter

Examples

# \donttest{

tmp <- tempfile()
# Write to existing connection with offset
con <- file(tmp, "wb")
writer <- BinaryWriter(con, byte_offset = 100L,
                      data_type = "integer", bytes_per_element = 4L)
unlink(tmp)
# }
