YplantQMC (version 0.6-3)

getangles: Read angles from a .p file.

Description

Reads leaf angles (angle, orientation or azimuth) from a plant file (a Yplant input file with extension .p, known as a pfile).

Usage

getangles(plant, whichangle = "An.3")

Arguments

plant

An object of class plant3d, or the name of a pfile.

whichangle

The name of the angle, in quotes (see modifypfile)

Value

• A vector of angles (in degrees).

Details

If the leaf angle is returned (An.3, the default), all angles are converted so that they are between 0 and 90 degrees. A warning is printed when any angle > 360, which may indicate problems in the data (this is uncommon). Other angles may be read, see modifypfile for a list of the angles in a pfile.

Examples

# Two options:
# Get leaf angles from a pfile
ang <- getangles("someplant.p")

# Or from a constructed plant:
myplant <- constructplant("someplant.p","someleaf.l")
ang <- getangles(myplant)
