R help - Dec 2007 - array() misfeature

Version: 2.5.1

array() is inconsistent when given non-integral dimensions:
> zz <- array(0,dim=c(4,3.01))
> dim(zz)
[1] 4 3
> zz <- array(0,dim=c(201,4.05))
Error in dim(data) <- dim : dim<- : dims [product 804] do not match the
length of object [814]


[IMHO the code that did this is broken.  My copy of it has been
fixed.  Consistent behavior and/or a clearer error message would
just have made it easier to find the problem.]

That's an obsolete version, but the issue is still present in R-devel.

I'll add code to coerce dim to integer before using it.  Thanks for the 
report.
