Running R function with arguments in 32 bit R, inside 64 bit R -

suppose want run function

test.function <- function(arg1){                     print(arg1)                  }   

how can run, lets say:

test.function("hello world") 

in 32 bit mode, using 64 bit r? have managed running entire script in 32 bit mode using

 system(paste0(sys.getenv("r_home"), "/bin/i386/rscript.exe ",'"some_script.r"'))    

but how can change this, can run function arguments, instead of entire script?

edit

following answer roman luštrik , running

system('rscript test.script.r "hello"') 

gives me following error:

error in windialog(type = "ok", message = message_text) : windialog() cannot used non-interactively call: -> check.for.updates.r -> windialog running stopped

warning message: running command 'rscript test.script.r "hello"' had status 1

(the error message in native language, had translate few words, text might differ on other systems)

you can't run specific function only, have create script. not stop creating one-function script, though.

if create script called test.script.r , put somewhere can find it.

args <- commandargs(trailingonly = true)  str(args)  test.function <- function(x) {   message("your input:")   message(x) }  invisible(sapply(args, test.function)) 

open terminal window. can use windows' cmd.exe (press windows key , type cmd.exe or command prompt or whatever have in perhaps localized version of system). navigate script located , run using below command.

$ rscript test.script.r "hello" "hello" "won't tell me name" "i hate doors"  chr [1:4] "hello" "hello" "won't tell me name" ... input: hello input: hello input: won't tell me name input: hate doors 

or, use system same thing through r.

system('rscript test.script.r "hello" "hello" "won't tell me name" "i hate doors"') 

notice way use single , double quotes. single quotes on outer side. call assumes script located in workspace r looking. can change using setwd(), though.
