range to those outside the range, typically for graphing purposes.
Usage
constrain(x, xrange)
Arguments
x
A numeric vector of values to constrain.
xrange
A numeric vector of length two specifying the constraints, the minimum and
maximum value for x.
Value
A numeric vector, the same length as x, in which the minimum
constraint is assigned to values of x less than the minimum,
and the maximum constraint is assigned to values of x greater than
the maximum.
