nwsFetchFile {nws}

R Documentation

Fetch a Value and Write It to a File

Description

Fetch a value of a netWorkSpace variable and write it to a file.

Usage

## S4 method for signature 'netWorkSpace':
nwsFetchFile(.Object, xName, fObj)

Arguments

`.Object`	a netWorkSpace object.
`xName`	character string giving the name of the variable to find.
`fObj`	`file` object or character string specifying file to write data to.

Details

The nwsFetchFile method looks in the shared netWorkSpace .Object for a value bound to xName; if it finds such a value, nwsFetchFile writes the value to the specified file and removes it from the variable. If no value is found, nwsFetchFile blocks until a value for xName becomes available.

Examples

## Not run: 
ws <- netWorkSpace('nws example')
nwsStore(ws, 'x', 'Hello, world\n')
nwsFetchFile(ws, 'x', 'hello.txt')
## End(Not run)
