VALUE(
This function creates a double precision vector of the specified length.
The elements of the vector are all equal to LANG(0).
PARA
LANG(as.double) attempts to coerce its argument to be of
double type.
PARA
LANG(is.double) returns LANG(TRUE) or LANG(FALSE)
depending on whether its argument is of double type or not.
