piece {smoothSurv} | R Documentation |
Function to evaluate a left continuous piecewise constant function with a finite support.
piece(x, breaks, values)
x |
Vector of values where the piecewise constant function should be evaluated. |
breaks |
Vector of sorted breakpoints of the piecewise constant function. |
values |
Values of the piecewise constant function. It takes the value
value[i] on the interval (breaks[i], breaks[i+1]] .
The function is assumed to be zero outside its range specified
as (breaks[1], breaks[length(breaks)]] .
The length of the vector values must be equal to
length(breaks) - 1
|
The value of the piecewise constant function.
