In arnejohannesholmin/sonR: Library for reading, processing and converting sonar data to the TSD format

Returns a matrix of two columns representing x- and y-values of positions on a circle of radius 'r' and origin 'origin', defined by the angles given by 'ang' in a polar coordinate system centered at 'origin', or by 'x' or 'y' in a cartesian coordinate system.

Description

Returns a matrix of two columns representing x- and y-values of positions on a circle of radius 'r' and origin 'origin', defined by the angles given by 'ang' in a polar coordinate system centered at 'origin', or by 'x' or 'y' in a cartesian coordinate system.

Usage

circle(
  origin = c(0, 0),
  r = 1,
  ang = seq(0, 2 * pi, length.out = 100),
  x = NULL,
  y = NULL,
  n = 100
)

Arguments

origin	is the origin of the circle.
r	is the radius of the circle, possibly a vector of the same length as 'ang' for varying radius.
ang	is a vector of angles defining the point on the circle, as seen in a polar coordinate system centered at 'origin'.
x	is a vector of x-values at which the circle is caclulated.
y	is a vector of y-values at which the circle is caclulated.
n	is (if length(and)==2) the length of 'ang' as a sequence between its first and the second element.
