A bridge between R and Nim: https://t.co/PyGcvcL0IR #rstats @nim_lang @rstudiotips @rstatstweet

[Sebastian S. @Vindaar]

Basic prototype for an R ⇔ Nim bridge up and running. _Lot's_ of work remains to be done though.

Still, might need a guinea pig sometime soon (@lf_araujo__?).

#rstats coming soon to #rdatatable::fread -- native ISO 8601 date & time parsing.

I am quite happy with how fast it's turning out -- 400x faster to read a date from a file than to use https://t.co/2PltaBnlRb! (and 50x less memory)

300x faster vs. as.POSIXct

#rstats textConnection() is a function I only learned recently that's quite useful.

Basically, it treats a string object _already in R_ as a "file", so you can use other "file input" functions on it

e.g.: paste text from clipboard -> a string in R, & read with lines as elements

I've been experimenting with midi.
Load file, select/duplicate track, harmonize duplicate to the 3rd, and play :
midi$new("https://t.co/SnzGYdB8Xh")$
select(Violin1=Violin, Violin3=Violin)$
shift_degree(2, scale_major("a"), at = Violin3)$
play("Violin1","Violin3")

What happens when you start #rstats? Well, it's quite simple, it's just...

Love you for all you do, @climagic.

See our 'littler' project which sparks command-line joy via the 'r' command bringing #rstats and the R language to the command-line since 2006.
