intg {PROcess} | R Documentation |
This function calculates the integration of y with respect to x.
intg(y, x)
x |
a vector of real values, not necessarily sorted. |
y |
a vector of function values at x. |
(x,y)s are sorted according to ascending x values and then the integration is calculated as sum of the products of average of adjacent y values and the difference of adjacent x values.
