scale	Numeric between 0 and 1
rotate	Boolean specifying whether to relect tile in the y axis (i.e. turn upside down)
x	Numeric between 0 and 0.75 for horizontal translation
y	Numeric between 0 and 3^.5/2 (the height of an equilateral triangle of unit side length) for vertical translation

Value

A transformed tile

Examples

r <- (2*3^.5+4)^-1
h <- r * (3^.5+1)
big_tile <- data.frame(x = c(.5-r, .5, .5+r),
                       y = c(h, r, h))

put_tile(tile = big_tile, rotate = TRUE, x = .125)
