Hi All, I'm wondering why when passing a single numeric value that contains any decimals to diag() that the value is silently coerced to a integer for constructing an identify matrix. To me, an input like diag(5.435) seems fairly ambiguous and is more than likely a programming mistake, since it's not obvious that a 5x5 identity matrix should be created. I've seen some code where other writers have been burned on this as well, especially when trying extract diagonal elements but forget about the scalar case. A warning or message would help track this problem down really quickly to force the author to use diag(floor(5.435)) explicitly, if indeed that is there intention. Thoughts?
