Should the Value: section of the help page read: For an array (and hence in particular, for a matrix) dim retrieves the dim attribute of the object. It is NULL for a vector of mode integer.
This statement is true, but less general than It is NULL or a vector of mode integer. hence the latter is surely preferred. Z

Hi, if I do Z<-rnorm(50) Followed by Dim(Z) I get NULL. Is this correct? Shouldn't I get 50 instead?
No, because Z has no dim attribute. ?dim tells you: "For an array (and hence in particular, for a matrix) dim retrieves the dim attribute of the object. It is NULL or a vector of mode integer."
