`r64` - a c64/6502 assembler in R

==============================================================================

Full documentation is available here: [coolbutuseless.github.io/package/r64](https://coolbutuseless.github.io/package/r64)

Rationale

------------------------------------------------------------------------------

* Who *doesn't* want a compiler for a **1 MHz** 8-bit computer with 16 colours and a max resolution of 320x200?

* A 6502 assembler in R will allow for preparing/calculating 

  data in R and then incorporating directly into the assembly code. e.g. 

    * creating character sets 

    * computing animation paths

Features

------------------------------------------------------------------------------

General features

* Basic syntax only. Similar to TASS64 syntax.

* Settable program counter

    * e.g. `* = $0801`

* Defined variables

    * e.g. `border = $d020`

* Low/High byte extraction from symbol (similar to TASS)

    * e.g. `lda #%

  select(addr, label, line, opcommand, op, ophex, nbytes, hexbytes) %>%

  knitr::kable()

```
