nfer (version 1.1.3)

load: Load an nfer specification from a file.

Description

This function loads an existing nfer specification, stored in a file, into R in a format that can be used by the nfer::apply function. See http://nfer.io/ for information on how to write nfer specifications.

Usage

load(specfile, loglevel = 0)

Value

A handle to the nfer specification, loaded into R.

Arguments

specfile

The name of file containing the nfer specification to load.

loglevel

(Optional) The logging level to set (0-4), where 0 is only warnings and errors and 3 is debug. Default is 0.

Details

Nfer specifications consist of rules that describe a relationship between pairs of intervals. These relationships describe new intervals that can then be used to describe more intervals. The result is a hierarchy of intervals. Although the algorithm takes intervals as its input, event traces are actually the target, so events are converted to intervals with zero duration.

Examples

test <- nfer::load(system.file("extdata", "ops.nfer", package = "nfer"))
ssps <- nfer::load(system.file("extdata", "ssps.nfer", package = "nfer"), loglevel=1)
