Send an R object to a remote location

S3 generic to send an R object to a location that may be method-defined. Message objects encapsulate a payload along with an address, but other classes require a destination as the x argument, either through a FD class, or as a character hostname.

send(x, ...)
# S3 method for class 'Message'
send(x, header, payload=NULL, keep_conn=FALSE, ...)
# S3 method for class 'FD'
send(x, header, payload=NULL, keep_conn=FALSE, ...)
# S3 method for class 'character'
send(x, port, header, payload=NULL, keep_conn=FALSE, ...)

Arguments

x

Destination, or object encapsulating one, serving as S3 dispatch.

header

character header

payload

Object to send

keep_conn

Boolean flag to keep connection open

port

Integer port to bind to.

...

Passed on to further methods.

Value

Typically a File Descriptor of the connection if successful. -1L if connection is not kept.
