height {dendrometry} | R Documentation |
Height of Tree or any vertical Object
Description
Computes the height of tree, pillar, girder, mast or any vertical object. It allows either slope (in percent) or angle (in degrees or radians). No matter the relative position of the persons who measures the angle or the slope.
Usage
height(
distance,
top,
bottom,
type = c("angle", "slope"),
angleUnit = c("deg", "rad")
)
Arguments
distance |
numeric, vector of the horizontal distance between object and the person who measures angle. |
top , bottom |
numeric vector of top angle and bottom angle respectively (readings from a clinometer). |
type |
the type of |
angleUnit |
the unit of |
Value
A vector of heights.
Examples
height(10, 80, 17)
height(17, top = -18, bottom = -113)
height(distance = 18, top = 42, bottom = -12, type = "angle", angleUnit = "deg")
height(
distance = 18:21, top = 42:45, bottom = -12:-15, type = "angle",
angleUnit = "deg"
)
## Below shows warning messages

distance = 18:21, top = -42:-45, bottom = -12:-15, type = "angle",
angleUnit = "deg"
