## Convert raw values into Amiga integers

### Description

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

### Usage

```
rawToAmigaInt(x, bits = 8, signed = F)
```

### Arguments

`x` |
A vector of class |

`bits` |
Number of bits that represents the integer value. Should be 8 or a positive multitude of 8. |

`signed` |
A |

### Details

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 raw data into such integers. Note that WORD and UWORD are also referred to as SHORT and USHORT respectively.

### Value

A `numeric`

value (or a `vector`

of values),
representing the integer data represented by the provided
`raw`

data. Note that R defines `integer`

as 32-bit
signed integers and cannot store the 32-bit signed values.
Therefore a `numeric`

value is returned rather than an
explicit `integer`

.

### Examples

```
## Let's start by obtaining unsigned 8-bit integers:
rawToAmigaInt(as.raw(0:255))
## note that this is the same as:
as.numeric(as.raw(0:255))
## but with this function we can also get signed values:
rawToAmigaInt(as.raw(0:255), signed = TRUE)
## Furthermore 32 or 16-bit integers can also be obtained.
## Let's look at 16-bit integers:
rawToAmigaInt(as.raw(0:255), 16)
## Note that 16-bit integers require twice as many bytes
## as 8 bit integers:
length(rawToAmigaInt(as.raw(0:255), 16))
length(rawToAmigaInt(as.raw(0:255), 8))
```
