RSolve (Built-in Mathematica Symbol)

RSolve[eqn, a[n], n] solves a recurrence equation for a[n]. RSolve[{eqn_1, eqn_2, ...}, {a_1[n], a_2[n], ...}, n] solves a system of recurrence equations. RSolve[eqn, a[n_1, ...

RuleDelayed (Built-in Mathematica Symbol)

lhs :> rhs or lhs :> rhs represents a rule that transforms lhs to rhs, evaluating rhs only after the rule is used.

Rule (Built-in Mathematica Symbol)

lhs -> rhs or lhs -> rhs represents a rule that transforms lhs to rhs.

RulerUnits (Built-in Mathematica Symbol)

RulerUnits is an option for notebooks that specifies the units in the ruler toolbar.

Run (Built-in Mathematica Symbol)

Run[expr_1, expr_2, ...] generates the printed form of the expressions expr_i, separated by spaces, and runs it as an external operating system command.

RunScheduledTask (Built-in Mathematica Symbol)

RunScheduledTask[expr] schedules and starts a task that will repeatedly evaluate expr once per second.RunScheduledTask[expr, time] schedules and starts a task that will ...

RuntimeAttributes (Built-in Mathematica Symbol)

RuntimeAttributes is an option for Compile that specifies attributes for the compiled function it creates.

SameQ (Built-in Mathematica Symbol)

lhs === rhs yields True if the expression lhs is identical to rhs, and yields False otherwise.

SameTest (Built-in Mathematica Symbol)

SameTest is an option whose setting gives a pairwise comparison function to determine whether expressions should be considered the same.

SampleDepth (Built-in Mathematica Symbol)

SampleDepth is an option for sound primitives that specifies how many bits should be used to encode sound amplitude levels.
