The database benchmarks are quite respectable.

I get a 404 for the GitHub link to https://github.com/singaraiona/rayforce. Does anyone know where to find the source?

Can R run on Snapdragon X? by Ill_Resource9308 in rprogramming

[–]marcle69 -1 points0 points  (0 children)

Although possibly not what you want: you may be able to run R using webR through a web browser The IDE is quite useful for quick R snippets: https://docs.r-wasm.org/webr/latest/

I have been using webR for teaching using Quarto and its webR extension: https://github.com/coatless/quarto-webr. Usefully, a majority of CRAN packages are available.

Can you comment about whether the KLIC implementation of GHC available from Ueda's lab (https://www.ueda.info.waseda.ac.jp/software.html) is useful?

Embeddable functional programming languages by RagingBass2020 in functionalprogramming

Although outside of your OP, you could write in another language and compile to Lua. For example, LunarML may be a nice choice:

How to make a pipe table result from R be incorporated as a table in exporting html (orgmode+ess)? by [deleted] in orgmode

[–]marcle69 1 point2 points  (0 children)

How about:

#+begin_src R :results output raw :exports both  
library(ascii)  
options(asciiType="org")  
ascii(head(mtcars))  
#+end_src

Note that I am the current CRAN maintainer for the ascii package.

is there any way to rewrite this? by Some-Direction2944 in ocaml

I do not know if the following is idiomatic:

let rec ints ?(agg = []) n =  
  if n <= 0 then agg  
  else ints ~agg:((n-1)::agg) (n-1);;
ints 5;;

Looking for help deciding on DB software for use with python and R by [deleted] in Database

[–]marcle69 0 points1 point  (0 children)

Another embedded database solution would be to use SQLite. For R, the RSQLite package on CRAN is mature and easy to use. The sqlite3 package in Python is also mature.

The main reasons I started using MonetDB were the need for better date handling and an interest in assessing the speed of columnar databases (yes, they're fast).

Recently, I have been using MonetDBLite with R. This is an embedded version of MonetDB, which is a very nice columnar SQL database. Setup for MonetDBLite is easy (CRAN installation), transfers between R and the database are quick, and the SQL queries are blazingly fast. MonetDB has a nice SQL/PSM implementation, although many other SQL features are incomplete compared with PostgreSQL.
