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 = 'cm', dstTarget = 100, conversion = 'm2cm',
           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<

unit

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

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. 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.
