Details. as.character and is.character are generic: you can write methods to handle specific classes of objects, see InternalMethods. Further, for as.character the default method calls as.vector, so dispatch is first on methods for as.character and then for methods for as.vector.
But this is the number of stars we can see from the entire Earth and we should remember that one hemisphere of Earth is always in daylight, so really only about 2500 to 5000 stars are visible at night from any given point on Earth.
And far away from any light pollution, you can see about 2,000 to 2,500 stars in the sky at one time. A similar number of stars lie unseen over the horizon. Youâll see them in six months, once the Earth revolves halfway around the Sun and the night sky points to the other half of the heavens.
