RClient: LuaJIT Client for Rserve
LuaJIT client for Rserve which is used to host a (local or remote) R session toward which a connection is established.
Features
- exchange data between LuaJIT and R (arrays, matrices, lists, data.frames)
- execute arbitrary R code from LuaJIT
local R = require "rclient"
local r = R.connect()
-- Lua --> R:
r.myvec = { 1,2,3 } -- Array.
r.mymat = R.asmatrix({ {1,2,3},{4,5,6} })
r.mylist = R.aslist({ 7,8,9 }, { "a","b","c" })
r.mydf = R.asdataframe({ 7,8,9 }, { "a","b","c" }, { "row1" })
-- Execute R commands and evaluate expression as in R interpreter:
r "myvec <- myvec^2"
r "myvec" --> [1] 1 4 9
-- R --> Lua:
local vec = r.myvec
local mat = r.mymat
local list = r.mylist
local df = r.mydf
print(unpack(vec)) --> 1 4 9
print(unpack(mat[1])) --> 1 2 3
print(unpack(mat[2])) --> 4 5 6
print(unpack(list[0][1])) --> a b c
print(list[1][1], list[2][1], list[3][1]) --> 7 8 9
print(list.a[1], list.b[1], list.c[1] ) --> 7 8 9
print(unpack(df[0][1])) --> a b c
print(unpack(df[0][2])) --> row1
print(df[1][1], df[2][1], df[3][1]) --> 7 8 9
print(df.a[1], df.b[1], df.c[1] ) --> 7 8 9Install
This module is included in the ULua distribution, to install it use:
upkg add rclient
Alternatively, manually install this module making sure that all dependencies listed in the require section of __meta.lua are installed as well (dependencies starting with clib_ are standard C dynamic libraries).
