set_label: Attach a label to an expression

In CVXR: Disciplined Convex Optimization

Attach a label to an expression

Description

Usage

set_label(x, value)

Arguments

x	An Expression object.
value	A label (character; coerced via as.character). Pass NULL to clear an existing label.

Value

x with the label updated.
