drawTarget: Draw a target pattern

Description

Draws a target pattern - either from the name of a pre-specified target type or from a supplied list defining the target.

Usage

drawTarget(x, unit, dstTarget, conversion,
           add = FALSE, cex = par('cex'))

Arguments

x

either a character value with the name of a target in targets or a list with a target definition containing the same components as those in targets (see below).

unit

the measurement unit that should be used in the plot. Possible values are 'cm', 'mm', 'm', 'in', 'ft', 'yd', 'deg', 'MOA', 'SMOA', 'rad', 'mrad', 'mil'.

dstTarget

a numerical value with the distance to the target - used in MOA calculation. See getMOA.

conversion

how to convert the measurement unit for distance to target to that of the (x,y)-coordinates - used in MOA calculation. Example 'm2cm'. See getMOA.

add

logical: add to existing plot or create new plot?

cex

numerical value specifying the magnification factor for plotting the ring numbers.

Value

Invisibly returns a list with (at least) the following components defining the target:

name

target name.

unitTarget

measurement unit for ring diameters and radii.

nRings

number of rings.

maxCount

highest ring count for scoring.

ringD10

diameter of ring number 10 (highest-valued ring).

ringD10i

diameter of sub-division of ring number 10 (Innenzehn). If target has no sub-division, equal to ringD10.

ringW

width of the remaining rings number 9, 8, 7, ...

cols

nRings+1 colors of the rings - right half of the target, starting with the sub-division of ring number 10 and going outwards.

colsTxt

nRings-1 colors of the ring numbers, starting with ring number 9 and going outwards.

ringR

nRings+1 ring radii, including sub-division of ring number 10.

unitConv

measurement unit for ringD10u, ringD10iu, ringWu, ringRu as defined by unit.

ringD10u

diameter of ring number 10 converted to unit.

ringD10iu

diameter of sub-division of ring number 10 (Innenzehn) converted to unit.

ringWu

width of the remaining rings number 9, 8, 7, ... converted to unit.

ringRu

nRings+1 ring radii, including sub-division of ring number 10, converted to unit.
