nws (version 1.2.3)

nwsStore-methods: netWorkSpace Class Method

Description

Store something to the shared netWorkSpace.

Usage

nwsStore(.Object, xName, xVal)

Arguments

.Object

a netWorkSpace class object

xName

name of the variable to be stored

xVal

value to be stored

Details

nwsStore associates the value xVal with the variable xName in the shared netWorkSpace corresponding to .Object, thereby making the value available to all the distributed R processes. If a mode has not already been set for xName, 'fifo' will be used (see nwsDeclare).

Note that, by default ('fifo' mode), nwsStore is not idempotent: repeating nwsStore(nws, xName, xVal) will add additional values to the set of values associated with the variable named xName. See the examples below for details.

Examples

ws = new('netWorkSpace', 'nws example')

# To store value 5 bound to variable 'x' on the netWorkSpace 'ws'
# (If 'x' was declared, then its mode is inherited, 
# otherwise 'x' uses the default mode 'fifo')
nwsStore(ws, 'x', 5)

# store 10 values associate with variable y to the netWorkSpace
for (i in 1:10)
nwsStore(ws, 'y', i)

# retrieve 10 values associate with variable y from the netWorkSpace
for (i in 1:10)
print(nwsFetch(ws, 'y'))
