I was trying to figure out if there is a function in R that tests if R object contains only integers. I though "is.integer" would be it, but this function only checks "whether its argument is of integer type or not". As a result

	x = (1:5)^2

Returns false. Of course I can write my own function like "!any(x!=as.integer(x))" but I am just trying to make sure I am not reinventing the wheel.
