Read and mutate virtual Commodore Amiga Disks, stored as files (a.k.a Amiga Disk Files).
Get CRAN version
Get development version from R-Universe
The package comes with an example disk for which files and directories can be listed:
library(adfExplorer)
data("adf.example")
list.adf.files(adf.example)
#> [1] "Devs" "S" "this" "mods"You can also pull files from the virtual disk:
## get startup-sequence file and store as a vector of raw data
startup <- get.adf.file(adf.example, "DF0:s/startup-sequence")
## As this particular file is UTF8 text we can convert it from raw:
startup |> rawToChar() |> iconv(from = "ISO-8859-1", to = "UTF-8") |> cat()
#> ; The Startup-Sequence is executed after booting
#> ; Everything after semicolons are comments and is ignored
#> ; By default standard commands are loaded from
#> ; the ROM kickstart. Additional commands should be
#> ; stored on the disk in the SYS:C directory.
#> ; For demonstration purposes we only echo some
#> ; text to the screen... Note that this will not
#> ; work on Amiga OS <2.0 as "Echo" is not available
#> ; in older ROM kickstart versions.
#>
#> Echo "c[22m[32mADF Explorer Example Disk" ; Note that the weird characters at the start are escape-codes to format the text
#> Echo "[0mThis disk was created as an example for the"
#> Echo "R package 'adfExplorer' by Pepijn de Vries."For more in depth examples see vignette("amigaDiskFiles").
It has been years since the initial release of this package. Since its release a lot has changed in R and in my skill set. I still have plans for this package, but this requires drastic changes. Therefore, I will only apply minimal maintenance to this package. Meanwhile I will work on a complete overhaul which will be released in due time as a new package. This new package will:
But until then, please enjoy the current package as is.
