Create Binary Reader Object

Source: R/binary_io.R
BinaryReader.Rd

Create a new instance of the BinaryReader class for reading bulk binary data.

Usage

BinaryReader(
  input,
  byte_offset,
  data_type,
  bytes_per_element,
  endian = .Platform$endian,
  signed = TRUE
)

Arguments

input

Character string (file name) or connection object to read from

byte_offset

Integer specifying bytes to skip at start of input

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)

signed

Logical indicating if data type is signed (default: TRUE)

Value

An object of class BinaryReader

Examples

# \donttest{
# Create a temporary binary file
tmp <- tempfile()
writeBin(rnorm(100), tmp, size = 8)


# Read from existing connection with offset
con <- file(tmp, "rb")
reader <- BinaryReader(con, byte_offset=0,
                      data_type = "DOUBLE", bytes_per_element = 8L)
close(reader)

# Clean up
unlink(tmp)
# }
