Expr: Expr

In ganalytics: Interact with 'Google Analytics'

Description

Define a Google Analytics expression.

Usage

Expr(object, comparator, operand, metricScope = "")

## S4 method for signature '.expr,ANY'
Expr(object)

## S4 method for signature 'formula,ANY'
Expr(object, metricScope)

## S4 method for signature 'character,character'
Expr(object, comparator, operand,
  metricScope = "")

Arguments

object	A dimension or metric variable, or another object to be coerced to an .expr object.
comparator	The comparator to use for the expression.
operand	The operand to use for the expression.
metricScope	Optional scope to use in the case of metric variables for segmentation. Possible values include "perUser" or "perSession".

Methods (by class)

• object = .expr,comparator = ANY: Returns itself.

• object = formula,comparator = ANY: Use non-standard formula evaluation to define an expression. Accepts a formula in the form of: ~ <variable> <comparator> <operand> where only the <operand> is evaluated.

• object = character,comparator = character: Return an expression composed of the supplied variable, comparator and operand arguments.
