out_object(object, x, ...)

# S4 method for class 'object'
out_object(object, x, ...)

Arguments

object

Object of the object-class.

Numeric vector or matrix containing x- and y-coordinates to be checked.

...

Arguments passed on to in_object

Examples

# Let's create an object
my_circle <- circle(center = c(0, 0), radius = 1)

# Let's create a matrix of different coordinates of which the first is 
# inside of the object, the second on its circumference, and the third  
# outside of the object
coords <- rbind(c(0, 0), 
                c(1, 0), 
                c(2, 0))

# Let's do the test
out_object(my_circle, coords)
#> [1] FALSE  TRUE  TRUE
