In jjb: Balamuta Miscellaneous

Description Usage Arguments Value Author(s) Examples

Takes a default matrix and embeds circles within the matrix.

1	circle_matrix(m, n, x.center, y.center, r, f = 1)

`m`	A `int` that is the number of rows of the matrix
`n`	A `int` that is the number of the columns of the matrix.
`x.center`	A `vector` of x coordinate center position of the circle.
`y.center`	A `vector` of y coordinate center position of the circle.
`r`	A `vector` of integers denoting the different circle radii.
`f`	A `vector` of values that specify what the inside of the circles should be.

A matrix with circles imprinted within its dimensions.

# Generate a basic circle matrix
circle_matrix(10, 10, 3, 4, 2)

# Generate two circles within the matrix
circle_matrix(10, 20, c(3,6), c(4,6), c(2,2))

# Different fills
circle_matrix(10, 20, c(3,6), c(4,6), c(2,2), f = c(1,2))
