Examples

# Create a temporary binary file with test data
tmp <- tempfile()
con <- file(tmp, "wb")
test_data <- rnorm(100)
writeBin(test_data, con, size = 8)
close(con)

# Create a BinaryReader and read the data
reader <- BinaryReader(tmp, byte_offset = 0L,
                      data_type = "double", bytes_per_element = 8L)
data <- read_elements(reader, 100)
close(reader)

# Clean up
unlink(tmp)

# Create a temporary binary file with some test data
tmp <- tempfile()
con <- file(tmp, "wb")
test_data <- rnorm(100)
writeBin(test_data, con, size = 8)
close(con)

# Create reader and read the data
reader <- BinaryReader(tmp, byte_offset = 0L,
                      data_type = "DOUBLE", bytes_per_element = 8L)
