bound: Set a Minimum or a Maximum or Both to a Vector.

In rpgm: Fast Simulation of Normal/Exponential Random Variables and Stochastic Differential Equations / Poisson Processes

Description

The function lbound sets a minimum to the elements of a vector, ubound a maximum and bound both.

Usage

lbound(x, m)
ubound(x, M)
bound(x, m, M)

Arguments

x	double, vector to put in [m, M].
m	double, the minimum.
M	double, the maximum.

Value

A vector with the values of x on which all values lower that m has been replaced by m and all values greater than M has been replace by M.

Note

x <- lbound(x, a) replaces x <- x*(x >= a) + a*(x < a) and x[x < a] <- a in a much faster way.
