comment Incomplete implementation of units?
I was thinking (perhaps incorrectly) that TargetUnits only applied to the output scale and that it wouldn't change the structure of a figure. I still believe that the proper way to address this question would be to add units to specs such as bspec.

comment Is there a “No Units” (i.e., dimensionless) unit?
@Rojo: I still found your answer helpful because it forced me to (finally) learn something about unprotecting symbols. I think you should keep your answer.

comment Is there a “No Units” (i.e., dimensionless) unit?
@Rojo: I run Monte Carlo simulations which output huge quantities of data with varying dimensions, so I created a data dictionary which describes each data type, including the units. When the simulation results are loaded into Mathematica, I use the data dictionary to attach units. However, some of the data types are dimensionless and rather than having a special "dimensionless" case for the code that calls Quantity, I'd rather have Quantity handle it.

Add my name to the list.

comment How to Debug Missing[NotAvailable] error for Social Media Data
I also have a full Mathematica license and I get the same error message. I wonder if it has something to do with privacy settings in Facebook.

@Szabolcs: I think you're right--that's basically the same question. Unfortunately, I was hoping for a simple "type this" answer, but it doesn't look like that's the case. Should I withdraw this question?

comment Should 0 * 5ft be 0 or 0ft?
@NasserM.Abbasi: the fact that the behavior changed from MMA7 to MMA8 leads me to think that the problem can be fixed.

comment Should 0 * 5ft be 0 or 0ft?
This has come up in the past. I posted the following message on comp.soft-sys.math.mathematica back in 2010: "While testing Mathematica 8 on some heritage code, I found a problem which a colleague traced to a behavioral change in Times[]. Specifically, the documentation for Times[] states that "0 x evaluates to 0, but 0.0 x is left unchanged." This appears to be true in Mathematica 7 but not in Mathematica 8 (at least not under Mac OS X 10.6.4). I have informed Wolfram about this change (bug?)" I don't think I ever received a satisfactory answer (they acknowledged the problem, but no fix).

comment How do I create a histogram out of this datastructure: x[i] = value_i?
And to answer your first question, a is a symbol. a={2,3,6} would be a list.

Do you want an histogram or a bar chart? I suspect you want a bar chart, in which case a={2,3,6}; BarChart[a]
