| real {base} | R Documentation |
real creates a double precision vector of the specified
length. Each element of the vector is equal to 0.
as.real attempts to coerce its argument to be of real type.
is.real returns TRUE or FALSE depending on
whether its argument is of real type or not.
real(length = 0) as.real(x, ...) is.real(x)
R has no single precision data type. All real numbers are stored in double precision format.
