Description Usage Arguments Details Value Author(s) See Also Examples

Convert 8, 16, or 32-bit signed or unsigned integer values into raw data, conform Amiga specifications.

1	amigaIntToRaw(x, bits = 8, signed = F)

`x`	A vector of class `numeric` which needs to be converted into raw values.
`bits`	Number of bits that represents the integer value. Should be 8 or a positive multitude of 8.
`signed`	A `logical` value indicating whether the numeric values is signed (`TRUE`, default) or not (`FALSE`).

The Commodore Amiga has specified the following data formats to represent integer data: BYTE (signed 8-bit integer), UBYTE (unsigned 8-bit integer), WORD (signed 16-bit integer), UWORD (unsigned 16-bit integer), LONG (signed 32-bit integer), ULONG, (unsigned 32-bit integer). This function converts such integers into raw data.

Returns (a vector of) raw data, representing the integer value(s) conform Amiga specifications.

## some unsigned 8-bit integers:
ubyte <- sample.int(255, 100, TRUE)

## The same values as raw data:
amigaIntToRaw(ubyte)

## some signed 8-bit integers:
byte <- sample.int(255, 100, TRUE) - 128

## The same values as raw data:
amigaIntToRaw(byte, signed = TRUE)

## some signed 16-bit integers:
word <- sample.int(2^16, 100, TRUE) - 2^15

## The same values as raw data:
amigaIntToRaw(word, 16, TRUE)

## note that 16-bit integers require
## twice as many raw values:
length(amigaIntToRaw(word, 16, TRUE))
length(amigaIntToRaw(byte, 8, TRUE))
