batch: Batch Execution

In wrathematics/remoter: Remote R: Control a Remote R Session from a Local One

Description

Run a local script on a remote server in batch. Similar to R's own source() function.

Usage

batch(
  addr = "localhost",
  port = 55555,
  password = NULL,
  file,
  script,
  timer = FALSE,
  serialversion = NULL
)

Arguments

addr	The remote host/address/endpoint.
port	The port (number) that will be used for communication between the client and server. The port value for the client and server must agree.
password	An initial password to pass to the server. If the server is not accepting passwords, then this argument is ignored. If the initial pasword is incorrect, then assuming the server's maxretry>1, then you will be interactively asked to enter the password.
file	A character string pointing to the file you wish to execute/source. Either this or script (but not both) should be provided.
script	A character string containing the commands you wish to execute/source. Either this or file (but not both) should be provided.
timer	Logical; should the "performance prompt", which shows timing statistics after every command, be used?
serialversion	NULL or numeric; the workspace format version to use when serializing. NULL specifies the current default version. The only other supported values are 2 and 3.

Details

Note that batch() can not be run from inside an active connection. Its purpose is to bypass the need to start a connection via client()

Value

Returns TRUE invisibly on successful exit.

Examples

## Not run: 
library(remoter)
### NOTE first run a server via remoter::server() )in a separate R session.
### For simplicity, assume they are on the same machine.

# Run a script in an R file on the local/client machine
file <- "/path/to/an/R/script.r"
batch(file=file)

# Run a script stored in a character vector
script <- "1+1"
batch(script="1+1")

## End(Not run)
