In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Write a sequence of elements from an input source

Description

Write a sequence of elements from an input source

Usage

write_elements(x, els)

Arguments

x	the output channel
els	the elements to write

Value

Invisibly returns NULL after writing the elements.

Examples

# Create a temporary binary file for writing
tmp <- tempfile()
writer <- BinaryWriter(tmp, byte_offset = 0L,
                      data_type = "DOUBLE", bytes_per_element = 8L)

# Write some random data
data <- rnorm(100)
write_elements(writer, data)
close(writer)

# Read back the data to verify
reader <- BinaryReader(tmp, byte_offset = 0L,
                      data_type = "double", bytes_per_element = 8L)
read_data <- read_elements(reader, 100)
close(reader)

# Verify data was written correctly
all.equal(data, read_data)

# Clean up
unlink(tmp)
