linfun(x, y, yleft = y[1], yright = y[length(y)])

Arguments

x, y

Numeric vectors giving the coordinates of the points to be interpolated.

yleft

The value to be returned when input x values are less than min(x).

yright

The value to be returned when input x values are greater than max(x).

Value

Objet of class linfun and function which is an approxfun function with method = 'linear'.
